Apply Wa_16018031267 / Wa_16018063123. This necessitates submitting a fastcolor blit as WABB and setting the copy engine arbitration to round-robin mode.
v2: - Rename old platform check in second patch to match declaration in first patch. - Refactor second patch name to match first patch. v3: - Move NEEDS_FASTCOLOR_BLT_WABB to intel_gt.h. - Refactor NEEDS_FASTCOLOR_BLT_WABB to make it more streamlined to use. - Stop dividing PAGE_SIZE by sizeof(u32) when computing ctx_bb_ggtt_addr for lrc_setup_bb_per_ctx. - Reduce comment complexity. - Fix several checkpatch warnings. v4: - Actually stop dividing PAGE_SIZE by sizeof(u32) when computing ctx_bb_ggtt_addr for lrc_setup_bb_per_ctx.
