Modify the SATA subsystem to add hotplug contexts to ACPI companions
of SATA devices and ports instead of registering special ACPI dock
operations using register_hotplug_dock_device().
That change will allow the entire code handling those special ACPI
dock operations to be dropped in the next commit.

Instead of requiring a set of special dock operations to be registered
via register_hotplug_dock_device() for each ACPI dock device, it is
much more straightforward to use callback pointers from the devices'
hotplug contexts if available.
For this reason, modify dock_hotplug_event() to use callback pointers
from the hotplug contexts of ACPI devices and fall back to using the
special dock operarions only if those callbacks are missing. Also
make the ACPI-based PCI hotplug (ACPIPHP) subsystem set the .fixup
callback pointer in the hotplug contexts of devices handled by it to
a new function, acpiphp_post_dock_fixup(), so that the dock station
driver can use the callbacks from those contexts instead of special
dock operations registered via register_hotplug_dock_device().
Along with the above changes drop the ACPIPHP's dock operations that
are not necessary any more.

Some system's ACPI video backlight control interface is broken and the
native backlight control interface should be used by default. This patch
sets the use_native_backlight parameter to true for those systems so
that video backlight control interface will not be created. For detailed
models that are added here, reference the following list.
Note that the user specified kernel cmdline option will always have the
highest priority, i.e. if use_native_backlight=0 is specified and the
system is in the DMI table, the video module will not skip registering
backlight interface for it.

Some devices have duplicate entries in there brightness levels table, ie
on my Dell Latitude E6430 the table looks like this:
[ 3.686060] acpi backlight index 0, val 80
[ 3.686095] acpi backlight index 1, val 50
[ 3.686122] acpi backlight index 2, val 5
[ 3.686147] acpi backlight index 3, val 5
[ 3.686172] acpi backlight index 4, val 5
[ 3.686197] acpi backlight index 5, val 5
[ 3.686223] acpi backlight index 6, val 5
[ 3.686248] acpi backlight index 7, val 5
[ 3.686273] acpi backlight index 8, val 6
[ 3.686332] acpi backlight index 9, val 7
[ 3.686356] acpi backlight index 10, val 8
[ 3.686380] acpi backlight index 11, val 9
etc.
Notice that brightness values 0-5 are all mapped to 5. This means that
if userspace writes any value between 0 and 5 to the brightness sysfs attribute
and then reads it, it will always return 0, which is somewhat unexpected.
This is a problem for ie gnome-settings-daemon, which uses read-modify-write
logic when the users presses the brightness up or down keys. This is done
this way to take brightness changes from other sources into account.
On this specific laptop what happens once the brightness has been set to 0,
is that gsd reads 0, adds 5, writes 5, and on the next brightness up key press
again reads 0, so things get stuck at the lowest brightness setting.
Filtering out the duplicate table entries, makes any write to brightness
read back as the written value as one would expect, fixing this.

The ACPI dock station code carries out an extra namespace scan
before the main one in order to find and register all of the dock
device objects. Then, it registers a notify handler for each of
them for handling dock events.
However, dock device objects need not be scanned for upfront. They
very well can be enumerated and registered during the first phase
of the main namespace scan, before attaching scan handlers and ACPI
drivers to ACPI device objects. Then, the dependent devices can be
added to the in the second phase. That makes it possible to drop
the extra namespace scan, so do it.
Moreover, it is not necessary to register notify handlers for all
of the dock stations' namespace nodes, becuase notifications may
be dispatched from the global notify handler for them. Do that and
drop two functions used for dock notify handling, acpi_dock_deferred_cb()
and dock_notify_handler(), that aren't necessary any more.
Finally, some dock station objects have _HID objects matching the
ACPI container scan handler which causes it to claim those objects
and try to handle their hotplug, but that is not a good idea,
because those objects have their own special hotplug handling anyway.
For this reason, the hotplug_notify flag should not be set for ACPI
device objects representing dock stations and the container scan
handler should be made ignore those objects, so make that happen.

Sometimes, there might be bugs caused by unexpected AML which is compliant
to the Windows but not compliant to the Linux implementation.
There is a predefined validation mechanism implemented in ACPICA to repair
the unexpected AML evaluation results that are caused by the unexpected
AMLs. For example, BIOS may return misorder _CST result and the repair
mechanism can make an ascending order on the returned _CST package object
based on the C-state type.
This mechanism is quite useful to implement an AML interpreter with better
compliance with the real world where Windows is the de-facto standard and
BIOS codes are only tested on one platform thus not compliant to the
ACPI specification.
But if a compliance issue hasn't been figured out yet, it will be
difficult for developers to identify if the unexpected evaluation result
is caused by this mechanism or by the AML interpreter.
For example, _PR0 is expected to be a control method, but BIOS may use
Package: "Name(_PR0, Package(1) {P1PR})".
This boot option can disable the predefined validation mechanism so that
developers can make sure the root cause comes from the parser/executer.
This patch adds a new kernel parameter to disable this feature.
A build test has been made on a Dell Inspiron mini 1100 (i386 z530)
machine when this patch is applied and the corresponding boot test is
performed w/ or w/o the new kernel parameter specified.

In some cases it may be necessary to perform certain setup/cleanup
operations on a device object representing a physical device after
it has been associated with an ACPI companion by acpi_bind_one() or
before disassociating it from that companion by acpi_unbind_one(),
respectively. If there is a struct acpi_bus_type object for the
given device's bus type, the .setup()/.cleanup() callbacks from there
are executed for these purposes. However, an analogous mechanism will
be necessary for devices whose bus types don't have corresponding
struct acpi_bus_type objects and that have specific ACPI scan handlers.
For those devices, add new .bind() and .unbind() callbacks to struct
acpi_scan_handler that will be executed by acpi_platform_notify()
right after the given device has been associated with an ACPI
comapnion and by acpi_platform_notify_remove() right before calling
acpi_unbind_one() for that device, respectively.
To make that work for scan handlers registering new devices in their
.attach() callbacks, modify acpi_scan_attach_handler() to set the
ACPI device object's handler field before calling .attach() from the
scan handler at hand.
