drm/nouveau: Revert "bus: remove cpu_coherent flag"
This reverts commit aff51175cdbf345740ec9203eff88e772af88059. The commit caused fence timeouts within nvc0_screen_destroy and most likely other places as well. The most obvious effect is, that userspace processes take minutes to actually quit. Signed-off-by: Karol Herbst <karolherbst@gmail.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
