[PATCH 0/2] Fixes for MI_REPORT_PERF_COUNT

[Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com>]

OA programming sequence for query mode or MI_REPORT_PERF_COUNT requires
modifying some HW registers in the same hw context as the user exec
queue. User passes the exec_queue to the OA interface and OA
implementation submits an MI_LOAD_REGISTER_IMM to this queue to modify
the registers.

The OA implementation submits a batch mapped in GGTT to the user exec
queue and hence, some plumbing is added into relevant code to enable
that (as per suggestions from Matthew Brost).

v2: review rework
v3:
- review rework
- original patches squashed for porting to stable
- code cleanup

opens:
- Should the cleanup patch be squashed as well and sent to stable? I have kept
  it separate hoping the build does not complain about dead code!!
- Applying these patches to stable is not clean since there is a dependency on
  another patch - "drm/xe: Force write completion of MI_STORE_DATA_IMM". Not
  sure if dependent patches need to be sent to stable as well.
