drm/radeon: properly handle mc_stop/mc_resume on evergreen+ (v2)
commit 62444b7462a2b98bc78d68736c03a7c4e66ba7e2 upstream.
- Stop the displays from accessing the FB
- Block CPU access
- Turn off MC client access
This should fix issues some users have seen, especially
with UEFI, when changing the MC FB location that result
in hangs or display corruption.
v2: fix crtc enabled check noticed by Luca Tettamanti
