[PATCH v2 0/3] Refactor functions implementing the blt batch buffer

[Balasubramani Vivekanandan <balasubramani.vivekanandan@intel.com>]

Functions implementing batch buffer for blitter instructions MEM_SET,
MEM_COPY, XY_FAST_COPY and XY_FAST_COLOR use a fixed instruction length
hardcoded inside the function.
In future platforms the length of these instructions will be increased.
Replace those fixed instruction length with a function which returns the
length of the instruction based on the platform.
For now those functions still return the fixed length but will be
extended while adding support for future platforms.
This series is a prep work for supporting the upcoming platforms.

v2:
- Removed the macros defining the instruction length so that no one in
  future directly makes use of it (Matt)
- Rebased on recent drm-tip

Balasubramani Vivekanandan (3):
  drm/xe: Refactor emit_clear_main_copy
  drm/xe: Refactor emit_clear_link_copy
  drm/xe: Refactor emit_xy_fast_copy and emit_mem_copy functions
