[igt-dev] [PATCH i-g-t v2] tests/kms_plane: allow pixel-format tests to run on drivers without legacy LUT

[Maíra Canal]

Currently, the tests pixel-format and pixel-format-source-clamping
fail for drivers that doesn't have support for legacy LUT, as they
are not able to complete drmModeCrtcSetGamma() successfully. Therefore,
if !crtc->gamma_size, don't set legacy LUT and allow the pixel-format
tests to run even if the driver doesn't support legacy LUT.
