[v2,0/3] 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.
