Subject: drm/i915/tgl: the BCS engine supports relative MMIO
Git-commit: ba2c74da52eba388d959a1000a9dd08fa4857659
Patch-mainline: v5.5-rc1
References: bsc#1152489
The specs don't mention any specific HW limitation on the blitter and
manual inspection shows that the HW does set the relative MMIO bit in
the LRI of the blitter context image, so we can remove our limitations.
