drm/amd/display: Correct sequences and delays for DCN35 PG & RCG
[why]
The current PG & RCG programming in driver has some gaps and incorrect
sequences.
[how]
Added delays after ungating clocks to allow ramp up, increased polling
to allow more time for power up, and removed the incorrect sequences.
