drm/amd/display: use new vblank enable policy for DCN35+
Hook up drm_crtc_vblank_on_config() in amdgpu_dm. So, that we can enable
PSR and other static screen optimizations more quickly, while avoiding
stuttering issues that are accompanied by the following dmesg error:
[drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3
This also allows us to mimic how vblanking is handled by the Windows
amdgpu driver. Specifically, we wait two idle frames before disabling
the vblank timer there.
