I'd prefer to have this go through asdn and the regular promotion testing.
One thing that some internal folks raised is that the DMUB timeout
`MAX_WAIT_US` might be too short. On some panels, backlight control are known
to take 250ms+. Triggering a DMUB reset rather than falling through may have
unintended consequences.
I'll spin something up for that soon-ish.
