[PATCH v3 2/9] dt-bindings: mediatek: Add gamma compatible for mt8195

[Jason-JH.Lin]

From: "zheng-yan.chen" <zheng-yan.chen at mediatek.com>

mt8195 uses 10bit-to-12bit gamma-LUT, which is not compatible with
current 9bit-to-10bit gamma-LUT.

This patch thus add constant compatible for mt8195, which means that
mt8195 should only use specified mt8195 gamma driver data.

Also, delete related compatible from enum, to ensure that
mt8195 will not accidentally get others' gamma driver data and thus
cause fatal error.
