drm/nv50-nvc0: request and wait on notification of modeset completion
This should prevent a number of races from occuring, the most obvious of which will be exposed when we start making use of the "display sync" evo channel for page flipping. The DS channel will reject any command stream that doesn't completely agree with the current "master" state. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
