Fix a race where a pending interrupt could be received and the handler
called before the handler's data has been setup, by moving the call to
irq_set_chained_handler() after the function which sets up the handler
data.

If the default PM domain using PM_CLK is used for PM runtime, the real PM
domain(s) cannot be registered from DT later.
Hence do not enable it when running a multi-platform kernel with genpd
support on an r8a73a4. The R-Mobile PM domain driver will take care of
PM runtime management of the module clocks.
The default PM domain is still needed for:
- platforms without genpd support,
- the legacy (non-DT) case, where genpd may take over later, except
for the C5 "always on" PM domain.

If we override the platform bus calls for pm_runtime then we end up
with the calls to the devices' suspend and resume methods ignored
in favour of the bus ones.
Change to calling the pm_runtime calls to suspend and resume the
devices specifically in the drivers/sh/pm_runtime.c implementation
to allow any device that may want to run power management to do so.
Note, all the current sh driver implementations do not use their
own power management code so this is not a major implementation
issues.
This also brings the implementation into line with the versions
used by the Davinci and Keystone PM domain code, so once fully
tested these implementations could be merged together.

If the kernel is built to support multi-ARM configuration with shmobile
support built in, then drivers/sh is not built. This contains the PM
runtime code in drivers/sh/pm_runtime.c, which implicitly enables the
module clocks for all devices, and thus is quite essential.
Without this, the state of clocks depends on implicit reset state, or on
the bootloader.
If ARCH_SHMOBILE_MULTI then build the drivers/sh directory, but ensure that
bits that may conflict (drivers/sh/clk if the common clock framework is
enabled) or are not used (drivers/sh/intc), are not built.
Also, only enable the PM runtime code when actually running on a shmobile
SoCs that needs it.
ARCH_SHMOBILE_MULTI was added a while ago by commit
efacfce5f8 ("ARM: shmobile: Introduce
ARCH_SHMOBILE_MULTI"), but drivers/sh was compiled for both
ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI until commit
bf98c1eac1 ("ARM: Rename ARCH_SHMOBILE to
ARCH_SHMOBILE_LEGACY").

The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core. It only is useful
for cpufreq drivers for their internal purposes.
Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.
Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0. If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.
Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.
To reduce overall code bloat, make the changes described above.

It was already pointed out how to fix these cases before the offending
patches were merged, but unsurprisingly, that didn't happen. As this
change is entirely superfluous to begin with, simply shut things up by
casting everything away.

This is a pretty significant branch. It's the introduction of the
first multiplatform support on ARM, and with this (and the later
branch) merged, it is now possible to build one kernel that contains
support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
platforms will be convered over in the next few releases.
Two critical last things had to be done for this to be practical and
possible:
* Today each platform has its own include directory under
mach-<mach>/include/mach/*, and traditionally that is where a lot of
driver/platform shared definitions have gone, such as platform data
structures. They now need to move out to a common location instead,
and this branch moves a large number of those out to
include/linux/platform_data.
* Each platform used to list the device trees to compile for its
boards in mach-<mach>/Makefile.boot.
Both of the above changes will mean that there are some merge
conflicts to come (and some to resolve here). It's a one-time move and
once it settles in, we should be good for quite a while. Sorry for the
overhead.

Some drivers need to switch pin states between GPIO and pin function at
runtime, which was inadvertently broken in the pinctrl driver for GPIOs
being bound to a specific direction.
This fixes up the request path to ensure that previously configured GPIOs
don't cause us to inadvertently error out with an unsupported mux on
reconfig, which in practice is primarily aimed at trapping pull-up/down
users that have yet to be implemented under the new API.
Fixes up regressions in the TPU PWM driver, amongst others.
