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

[Stuart Summers]

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)
v5: Make the G2H buffer size 64K (Matt)
v6: Rebase and resend for CI
v7: Rebase (again) and resend for CI
    The prior series was showing an unexpected failure in some
    of the display tests. I tried running the main one manually
    after rebasing this series again recently and it passed
    on manual execution, so giving this series another try on CI
    with the expectation that those prior issues were unrelated
    to my series. Here's the test I ran manually:
    igt at kms_cursor_edge_walk@64x64-top-bottom
