msm: mdss: Add gamma correction support in mdp3
Add gamma correction support in mdp3 driver via
MSMFB_MDP_PP ioctl. The ioctl has been extended to
program luts corresponding to histogram based
outputs and gamma correction based on flag.
The gain corresponding to gamma correction and
the histogram based output are combined in driver
and applied to hardware.
