Introduce an xe_bo_create_pin_map_novm() function that does not
take the drm_exec paramenter to simplify the conversion of many
callsites.
For the rest, ensure that the same drm_exec context that was used
for locking the vm is passed down to validation.
Use xe_validation_guard() where appropriate.
v2:
- Avoid gotos from within xe_validation_guard(). (Matt Brost)
- Break out the change to pf_provision_vf_lmem8 to a separate
patch.
- Adapt to signature change of xe_validation_guard().

GuC provides support to read engine counters to calculate the
engine activity. KMD exposes two counters via the PMU interface to
calculate engine activity
Engine Active Ticks(engine-active-ticks) - active ticks of engine
Engine Total Ticks (engine-total-ticks) - total ticks of engine
Engine activity percentage can be calculated as below
Engine activity % = (engine active ticks/engine total ticks) * 100.
