media: ccs-pll: Add support for decoupled OP domain calculation

Add support for decoupled OP domain clock calculation. This means that the
number of VT and OP domain clocks are no longer dependent on the number of
CSI-2 lanes in the lane speed mode.

The support also replaces the existing quirk flag to calculate OP domain
clocks per lane.

Also support decoupled OP domain calculation in the CCS driver.

media: smiapp-pll: Rename as ccs-pll

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.

media: ccs: Combine revision number major and minor into one

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.

media: ccs: Make hwcfg part of the device specific struct

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

media: smiapp: Rename as "ccs"

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.
