Add support for Ccm and Gamma to the Mali-C55 ISP by defining the
corresponding blocks in the uAPI and implementing their handling in
the driver.
v3 implements validation of CCM and Gamma parameters using the new
block_validate() callback from v4l2-isp.
I kept the two patches unsquashed, to discuss if it is worth validating
the fields or we should rely on masking before writing to registers.
