This series introduces support for
* drm_colorop DRM objects
* COLOR_PIPELINE plane property

Kernel changes:
https://gitlab.freedesktop.org/hwentland/linux/-/merge_requests/5

libdrm changes:
https://gitlab.freedesktop.org/hwentland/drm/-/merge_requests/1

It also adds a new kms_colorop test case that tests the color pipeline
API. The tests are designed to be easily extensible with a "transform"
and "compare" function pointer for each test. The "transform" function
performs the transformations under test via SW routines. The "compare"
function compares the DRM/KMS result (via a writeback connector) with
the result derived via the SW "transform".

Currently there are three tests:
 - plane-srgb_eotf: pre-blending sRGB EOTF
 - plane-srgb_inv_eotf: pre-blending sRGB Inverse EOTF
 - plane-srgb_eotf-srgb_inv_eotf: pre-blending sRGB EOTF,
   followed by its inverse
