drm/amdgpu: Set PFLIP_SUBMITTED for crtc after address update

Browse source

Also add some pflip debug prints.

This change allows us to wait on pflip status until the new surface address
is actually submitted to the register.

drm/amdgpu: Move MMIO flip out of spinlocked region
The original change assumed DAL will aquire locks inside DAL

This moves the flip before status update which makes sense for the
non-DAL code pathes as well.
