[igt-dev] [PATCH v3] tests/kms_plane: Handle hw without legacy gamma support

[Rob Clark <robdclark@gmail.com>]

From: Rob Clark <robdclark@chromium.org>

Skip the tests which require legacy gamma, instead of failing, if the hw
does not support legacy gamma.

v2: igt_require(lut_size > 0) instead
v3: simplify patch
