drm/amd/display: Set DCN32 to use update planes and stream version 3

Browse Source 
[Why]
Old minimal transition does not always wait for updates to complete
before proceeding, which can lead to corruption in multi display
scenarios for DCN32.

[How]
Set DCN32 to use update_planes_and_stream_v3 for better pipe transition
handling.
