[RFC PATCH v4 17/42] drm/vkms: Add enumerated 1D curve colorop

[Harry Wentland <harry.wentland@amd.com>]

This patch introduces a VKMS color pipeline that includes two
drm_colorops for named transfer functions. For now the only ones
supported are sRGB EOTF, sRGB Inverse EOTF, and a Linear TF.
We will expand this in the future but I don't want to do so
without accompanying IGT tests.

We introduce a new vkms_luts.c file that hard-codes sRGB EOTF,
sRGB Inverse EOTF, and a linear EOTF LUT. These have been
generated with 256 entries each as IGT is currently testing
only 8 bpc surfaces. We will likely need higher precision
but I'm reluctant to make that change without clear indication
that we need it. We'll revisit and, if necessary, regenerate
the LUTs when we have IGT tests for higher precision buffers.

v4:
 - Drop _tf_ from color_pipeline init function
 - Pass supported TFs into colorop init
 - Create bypass pipeline in DRM helper (Pekka)

v2:
 - Add commit description
 - Fix sRGB EOTF LUT definition
 - Add linear and sRGB inverse EOTF LUTs
