From: Alex Hung <alex.hung@xxxxxxx>
This patch adds colorops for custom 1D LUTs in the SHAPER and
BLND HW blocks.
With this change the following IGT tests pass:
kms_colorop --run plane-XR30-XR30-srgb_inv_eotf_lut
kms_colorop --run plane-XR30-XR30-srgb_inv_eotf_lut-srgb_eotf_lut
The color pipeline now consists of the following colorops:
1. 1D curve colorop
2. 1D curve colorop
3. 1D LUT
4. 1D curve colorop
5. 1D LUT
The 1D curve colorops support sRGB, BT2020, and PQ scaled to 125.0.
