Since MT8195 supports GAMMA 12-bit LUT after the landing of [1] series, we can now add support for MT8188.

Since MT8195 gamma has multiple bank for 12 bits LUT and it is different from any other SoC LUT setting.
So we move MT8195 compatible from the one of items to the single enum group.

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.

Please keep this ordered by fallback compatible, so your list with 8195 fallback should go below the list here.
Best regards, Krzysztof

While I agree on allowing mt8195-disp-gamma to have its own separated compatible as the IP is actually different from the one in MT8183, you can't do it like that, or dtbs_check will fail validation for the mt8195 devicetree.
That one declares...
gamma0: gamma@1c006000 { compatible = "mediatek,mt8195-disp-gamma", "mediatek,mt8183-disp-gamma";
...Please always run dtbs_check when performing bindings modifications.
Cheers, Angelo
