drm/amd/display: Fix DMCUB loading sequence for DCN3.2

Browse source

[ Upstream commit 18e755155c ]

[Why]
New sequence from HW for reset and firmware reloading has been
provided that aims to stabilize the reload sequence in the case the
firmware is hung or has outstanding requests.

[How]
Update the sequence to remove the DMUIF reset and the redundant
writes in the release.
