From: Chris Wilson @ 2020-12-09 23:21 UTC (permalink / raw)
To: intel-gfx
Cleanup intel_lrc.h by moving some of the residual common register
definitions into intel_lrc_reg.h, prior to rebranding and splitting off
the submission backends.
v2: keep the SCHEDULE enum in the old file, since it is specific to the
gvt usage of the execlists submission backend (John)
