drm/amd/display: Reset VRR config during resume
[Why]
After resume the system, the new_crtc_state->vrr_infopacket does not
synchronize with the current state. It will affect the
update_freesync_state_on_stream() does not update the state correctly.
The previous patch causes a PSR SU regression that cannot let panel go
into self-refresh mode.
[How]
Reset the VRR config during resume to force update the VRR config later.
