Jacopo MondiandHans Verkuil 6962703102 media: mali-c55: Add support for RGB Gamma ...

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.
