[igt-dev] [PATCH igt] tests/kms_color: Gamma tests should require hw support

[Rob Clark]

From: Rob Clark <robdclark at chromium.org>

Some qcom devices support CTM but not gamma/degamma LUT.

Note, the remaining failures on msm are due to CTM being supported on
one CRTC but not the other.  But the property is exposed on both.
