[igt-dev] [PATCH i-g-t v4 6/7] tests/chamelium/kms_color_chamelium: MPO + pipe color test for gamma

[Ananya Sharma]

Adding multiple planes with two different formats i.e. RGB and
NV12 in pipe color test for gamma in kms_color_chamelium too
as we can expect crc mismatches due to the hardware round-ups
the LUT values. This will also increase the coverage in color
management.
