[PATCH i-g-t v7 0/2] Enable multi-format testing for pipe color tests

[Pranay Samala <pranay.samala@intel.com>]

This series adds multi-format coverage to kms_color pipe color tests.

To ensure deterministic behavior across YUV formats, the first patch
updates framebuffer creation to explicitly specify YCbCr encoding/range
instead of relying on implicit defaults.

The second patch extends gamma, degamma, and CTM tests to run across
multiple pixel formats at the dynamic subtest level. This adds coverage
for format-dependent color pipeline behavior while avoiding redundant
testing on platforms where only a single format is applicable.

v2:
- Add DRM_FORMAT_P010 format

v3:
- Update commit message (Swati)

v4:
- Split the patches (Swati)

v5:
- Consolidate format structure with bpc info (Swati)
- Move format support check out of dynamic subtest scope (Swati)
- Add a common FB helper to centralize framebuffer creation (Swati)
- Keep RGB formats on the existing igt_create_fb() path (Swati)
- Use explicit range/encoding only for YUV formats (Swati)

v6:
- Add FP16 format to the format list
- Combine declaration and assignment for mtk_10bpc_only (Swati)
- Use per-format depth in gamma/degamma tests for 10-bit accuracy (Swati)
- Rename fb creation helper name (Swati)
- Make YCbCr encoding and range explicit helper parameters (Swati)

v7:
- Rebase

  tests/kms_color: Prepare FB creation for explicit YUV color range
    handling
  tests/kms_color: Add multi-format coverage for pipe color tests
