Revert "amd/amdgpu: Disable VCN DPG mode for Picasso"

This reverts commit c6d2b0fbb893d5c7dda405aa0e7bcbecf1c75f98.

This patch is a workaround for a hardware bug, but I don't
know that we've actually seen the hw bug triggered in practice,
meanwhile a number of people have reported that this causes
suspend and resume issues.
