[PATCH 0/3] Update page fault queue size calculation

[Stuart Summers <stuart.summers@intel.com>]

Right now the page fault queue size is hard coded with an
estimated value based on legacy platforms. Add a more precise
calculation based on the number of compute resources available
which can utilize these page fault queues.

v2: Add a drm reset callback for the teardown changes and other
    suggestions from Matt.
v3: Add a pf_wq destroy when the access counter wq allocation
    fails (Rodrigo) and pf queue size calculation adjustment (Matt)
v4: Bump up the size of the G2H queue as well (Matt)

  drm/xe: Use topology to determine page fault queue size
  drm/xe/guc: Bump the G2H queue size to account for page faults
