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).

  xe: Allow a GGTT mapped batch to be submitted to user exec queue
  xe/oa: Use MI_LOAD_REGISTER_IMMEDIATE to enable OAR/OAC
