[PATCH 2/2] amd/amdgpu_dm: Verify Gamma and Degamma LUT sizes using DRM Core check

[Mark Yacoub <markyacoub@chromium.org>]

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.
