drm/radeon: remove vm_manager start/suspend
Just restore the page table instead. Addressing three
problem with this change:
1. Calling vm_manager_suspend in the suspend path is
problematic cause it wants to wait for the VM use
to end, which in case of a lockup never happens.
2. In case of a locked up memory controller
unbinding the VM seems to make it even more
unstable, creating an unrecoverable lockup
in the end.
3. If we want to backup/restore the leftover ring
content we must not unbind VMs in between.
