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)
