drm/amd/display: Test HDMI HPD debounce re-detect
[WHAT]
amdgpu_dm_hdmi_hpd_debounce_work() only ran with detection
failing, so neither outcome of the sink comparison that decides whether
an HPD toggle was spurious was covered.
[HOW]
Add a fixture for the debounce work item and two tests: a
re-detect finding the same sink, which re-enables internally without
notifying userspace, and one finding a different sink, which sends the
hotplug event.
