Add support for Gamma curve correction for the Mali C55 ISP.
Define a new block in the uAPI using the extensible v4l2-isp format and
implement support for configuring the RGB Gamma parameters in the
mali-c55 parameters handler.
While at it, rename the MALI_C55_REG_GAMMA_GAINS_[1|2] register name
to MALI_C55_REG_GAMMA_GAINS_[RG|B] and the
MALI_C55_REG_GAMMA_OFFSETS_[1|2] register name to
MALI_C55_REG_GAMMA_OFFSETS_[RG|B] to better clarify their intent.

The Mali C55 driver uses the v4l2-isp framework, which defines its own
versioning number which does not need to be defined again in each
platform-specific header.
Remove the definition of mali_c55_param_buffer_version enumeration from
the Mali C55 uAPI header.

Add definitions and documentation for the custom control that will
be needed by the Mali-C55 ISP driver. This will be a read only
bitmask of the driver's capabilities, informing userspace of which
blocks are fitted and which are absent.
