[Intel-gfx] [PATCH i-g-t 1/2] tests/kms_color: 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.

v2 - Addressed review comments from Bhanuprakash Modem
Changed full degamma for reference CRC to linear degamma
Added clean up of degamma end of degamma test.

v3 - Addressed review comments from Bhanuprakash Modem
Fixed comments
