drm/amd/display: add dm_dmub_hw_resume KUnit coverage

Browse source

[WHAT]
Extend KUnit coverage for dm_dmub_hw_resume() using the fake-DMUB
fixtures. New cases cover the already-initialized wait path, the full
reinitialization path, a failed init-state query, and an auto-load
timeout, none of which require real hardware.
