drm/amd/display: Add support for BT.709 and BT.2020 TFs
This adds support for the BT.709/BT.2020 transfer functions
on all current 1D curve plane colorops, i.e., on DEGAM, SHAPER,
and BLND blocks.
With this change the following IGT subtests pass:
kms_colorop --run plane-XR30-XR30-bt2020_inv_oetf
kms_colorop --run plane-XR30-XR30-bt2020_oetf
