drm/amd/display: Use physical addressing for DMCUB on both dcn20/21

Browse Source 
[Why]
CW0 and CW1 need to use physical addressing mode for dcn20 and dcn21.

The current code for dcn20 is using virtual.

[How]
We already program the DMCUB like this on dcn21 so we should just use
the same sequence for both.

Copy the dcn21 sequences into the dmjub_dcn20.c file and rename them.
