[v3,0/9] Add gamma lut support for mt8195

Message

Since the gamma_set_common() function for previous SoC,
such as  mt8173 and mt8183, is designed for 9bit-to-10bit
conversion.
mt8195 is using 10bit-to-12bit conversion, which is
not compatible with the previous function.

Thus, need to update the function to fit the need of mt8195.

Change in v3:
1. separate 1 dt-binding patch to 2 patches, 1 is for modifying
   multiple items list to one and 1 is for moving mt8195 compatible.
2. redefine variables to reduce memory usage.
3. delete unused symbols.
4. separate 1 drm/mediatek patch to 6 patches.
5. rebase on tag 'next-20220909'
