Harry Wentland Feb. 26, 2024, 9:10 p.m. UTC 
This patchset enables support for the PQ_125 EOTF and its inverse
on all existing plane 1D curve colorops, i.e., on DEGAM, SHAPER,
and BLND blocks.

With this patchset the following IGT subtests are passing:
kms_colorop --run plane-XR30-XR30-pq_125_eotf
kms_colorop --run plane-XR30-XR30-pq_125_inv_eotf
kms_colorop --run plane-XR30-XR30-pq_125_eotf-pq_125_inv_eotf
kms_colorop --run plane-XR30-XR30-pq_125_eotf-pq_125_inv_eotf-pq_125_eotf
