[PATCH i-g-t v3 0/6] Add FIXED_MATRIX colorop tests

[Swati Sharma <swati2.sharma@intel.com>]

Add support for testing the DRM FIXED_MATRIX colorop type, which
selects from predefined hardware color space conversion matrices
rather than programmable coefficients.

The series adds:
- UAPI definition for DRM_COLOROP_FIXED_MATRIX
- FIXED_MATRIX_TYPE property support in igt_kms
- Colorop helper support for configuring FIXED_MATRIX blocks
- Pipe-CRC based tests in kms_color_pipeline
- Chamelium frame-capture based tests in kms_chamelium_color_pipeline

With this, the SDR plane color pipeline looks like:

[YUV Full/Limited -> RGB] -> [1D LUT]

A single FIXED_MATRIX colorop handles both full and limited range
YCbCr to RGB conversion.

Supported FIXED_MATRIX modes:
  - YCbCr 601 Full to RGB
  - YCbCr 601 Limited to RGB
  - YCbCr 709 Full to RGB
  - YCbCr 709 Limited to RGB
  - YCbCr 2020 NC Full to RGB
  - YCbCr 2020 NC Limited to RGB

v2: -Naming changes (CSC_FF -> FIXED_MATRIX)
v3: -Drop YCbCr limited to full and RGB709 to RGB2020 matrices
     until we have non-IGT userspace that shows their use
    -Rename subtests to yuv-rgb-btXXX with limited range variants
    -Add limited range test coverage
