drm/i915/xehpsdv/dg1/tgl: Fix issue with LRI relative addressing
When bit 19 of MI_LOAD_REGISTER_IMM instruction opcode is set on tgl+
devices, HW does not care about certain register address offsets, but
instead check the following for valid address ranges on specific engines:
RCS && CCS: BITS(0 - 10)
BCS: BITS(0 - 11)
VECS && VCS: BITS(0 - 13)
Also, tgl+ now support relative addressing for BCS engine - So, this
patch fixes issue with live_gt_lrc selftest that is failing where there is
mismatch between LRC register layout generated during init and HW
default register offsets.
