From: Mark Yacoub markyacoub@google.com
[Why] drm_atomic_helper_check_crtc now verifies both legacy and non-legacy LUT sizes. There is no need to check it within amdgpu_dm_atomic_check.
[How] Remove the local call to verify LUT sizes and use DRM Core function instead.
Tested on ChromeOS Zork.
v1: Remove amdgpu_dm_verify_lut_sizes everywhere.
