drm/amdgpu/vcn: not pause dpg for unified queue
commit 7d75ef3736a025db441be652c8cc8e84044a215f upstream.
For unified queue, DPG pause for encoding is done inside VCN firmware,
so there is no need to pause dpg based on ring type in kernel.
For VCN3 and below, pausing DPG for encoding in kernel is still needed.
v2: add more comments
v3: update commit message
