[igt-dev] [PATCH i-g-t v2] tests/xe/xe_huc_copy: check debugfs for huc running

[Matt Atwood <matthew.s.atwood@intel.com>]

Use debugfs to make sure that huc is loaded for xe_huc_copy. This
test will eventually need to determine if huc failed to load or if the
platform supports it period.

v2: support multitile (Lucas)
