FIXME: It is suspected that some Address Translation Service (ATS)
issue on IOMMU is causing CAT errors to occur on some MTL workloads.
Applying a write barrier to the ppgtt set entry functions appeared
to have no effect, so we must temporarily use I915_MAP_WC in the
map_pt_dma class of functions on MTL until a proper ATS solution is
found.

When the driver unbinds, pmu is unregistered and i915->uabi_engines is
set to RB_ROOT. Due to this, when i915 PMU tries to stop the engine
events, it issues a warn_on because engine lookup fails.

All perf hooks are taking care of this using a pmu->closed flag that is
set when PMU unregisters. The stop event seems to have been left out.

Check for pmu->closed in pmu_event_stop as well.

The steering control and semaphore registers are inside an "always on"
power domain with respect to RC6.  However there are some issues if
higher-level platform sleep states are entering/exiting at the same time
these registers are accessed.  Grabbing GT forcewake and holding it over
the entire lock/steer/unlock cycle ensures that those sleep states have
been fully exited before we access these registers.

This is expected to become a formally documented/numbered workaround
soon.

Note that this patch alone isn't expected to have an immediately
noticeable impact on MCR (mis)behavior; an upcoming pcode firmware
update will also be necessary to provide the other half of this
workaround.

v2:
 - Move the forcewake inside the Xe_LPG-specific IP version check.  This
   should only be necessary on platforms that have a steering semaphore.
