Nikola Cornij 87de6cb2f2 drm/amd/display: Reset steer fifo before unblanking the stream
[why]
During mode transition steer fifo could overflow. Quite often it
recovers by itself, but sometimes it doesn't.

[how]
Add steer fifo reset before unblanking the stream. Also add a short
delay when resetting dig resync fifo to make sure register writes
don't end up back-to-back, in which case the HW might miss the reset
request.
