drm/amd/display: add check for PMFW hard min request complete

Browse source

[Why]
When we issue hard min request to PMFW, the ack back does not
guarantee the request has been fulfilled.

[How]
Add new PMFW message to check if the hard min request has been
completed. Returned bit mask indicates which clock requests are
completed. Check PMFW version before using message
