[igt-dev] [PATCH i-g-t 2/2] tests/kms_color_chamelium: Disable gamma in degamma tests

[Vidya Srinivas]

This patch disables gamma in degamma subtest which is missing.
It compares CRC between (linear degamma + solid colors) and (max
degamma + gradient colors). Patch also cleans up degamma before
exiting degamma test and cleans up gamma before exiting gamma
test.
