The preferred integer types in the kernel are the Linux specific ones,
switch from standard C types to u32 and alike.

The analogue gain control was stored to the device specific struct but was
never used. Remove it.

Use regulators vio and vcore besides vana. The regulators were always
there but on many boards they've been hard wired. Control them explicitly
now.

MIPI CCS replaces SMIA and SMIA++ as the current standard. CCS brings new
features while existing functionality will be supported. Rename the
smiapp-pll as ccs-pll accordingly.
Also add Intel copyright to the files.

Some limit values are available in q16.q16 format, referred to as 32-bit
unsigned ireal in CCS. Read these correctly.

Read the CCS static data for sensors and modules. The files are expected
to be found in "ccs" directory.

The module revision number major and minor are both 8 bits while the
sensor revision number is 16 bits. Combine the module revision into one
number.
This also adds printing the lowest 8 bits of the module version through
the sysfs attribute.

There's no need to allocate the hardware configuration struct separately.
Put it in struct ccs_sensor.

The DT bindings documented "reset-gpios" property but the driver never
made use of it. Instead it used a GPIO called "xshutdown", with apprently
wrong polarity.
Fix this by requesting "reset" GPIO with the right polarity first, and if
that fails, then request "xshutdown" GPIO with the old polarity. This way
it works for new users as expected while if someone, somewhere, depended
on "xshutdown" GPIO, that continues to work as well.

The driver doesn't do anything tangible with profiles. Remove the notion,
and use the capabilities directly.

Rename the "smiapp" driver as "ccs". MIPI CCS is the contemporary standard
for raw Bayer camera sensors. The driver retains support for the SMIA++
and SMIA compliant camera sensors. A module alias is added for old user
space using "smiapp" module name.
Add Intel copyright while at it.
