Subject: drm/amd/display: fix dcn20 odm dpp programming
Git-commit: 285e30049708c40a8b0221438d0300cb19a68eff
Patch-mainline: v5.4-rc1
References: bsc#1152489
dcn20 requires special casing for odm.
This change treats odm as alternative to mpc tree on dcn20.
This is planned to be fixed in a future refactor
