[Intel-xe] [PATCH v5 0/2] drm/xe: Skip XY_FAST_COLOR instruction on link copy engines

[Balasubramani Vivekanandan]

Use MEM_SET instructions as alternative on platforms with link copy
engines which does not support the XY_FAST_COLOR instruction.

v5:
  - Modified xe_migrate_clear() function to stop accepting values for
    setting. This function now only clears the memory region to 0. (Lucas)

v4:
  - Modified the patch such that when using MEM_SET instruction, only
    allow clearing the memory region, setting of value is not supported.
  - Adapt migrate sanity kunit tests for platforms with link copy
    engines (Niranjana).

v3:
  - bitmask definitions reorder with most significant bit first (Lucas)
  - s/GRAPHICS_VERx100(gt->xe)/GRAPHICS_VERx100(xe) (Niranjana)
