Since MT8195 gamma has multiple bank for 12 bits LUT and it is different from any other SoC LUT setting.

So we add MT8195 compatible to the single enum group to make its driver data settings can be reused by other SoC.

The gamma LUT setting of MT8188 and MT8195 are the same, so we create a one of items for MT8188 to reuse the driver data settings of MT8195.

Since MT8195 compatible is in the single enum group, we have to add its compatible into mediatek-drm component binding table to ensure that it can be bound as a ddp_comp.
