Normally on shutdown or reboot we don't care about necessarily
making sure the hw is in a good state because the system is about
to be powered down or reset. However, after a shutdown or reboot
in a VM, it's best to tear down the hw properly otherwise there
can be problems with the next VM use.

Lots of drivers don't properly compile without this when CONFIG_FB=n.
It's kinda a hack, but since CONFIG_FB doesn't stub any fucntions when
it's disabled I think it makes sense to add it to drm_fb_helper.h.
Long term we probably need to rethink all the logic to unload firmware
framebuffer drivers, at least if we want to be able to move away from
CONFIG_FB and fbcon.
v2: Unfortunately just stubbing out remove_conflicting_framebuffers in
drm_fb_helper.h upset gcc about static vs. non-static declarations, so
a new wrapper it needs to be. Means more churn :(

With the previous change, it's safe to let page flips take effect
anytime during a vertical blank period.
This can avoid delaying a flip by a frame in some cases where we get to

vertical blank period.

When this code was written, we didn't retry DP aux transactions on any
error, which required retrying important transactions like this in
individual drivers. Since that's no longer the case, retrying here is
not necessary. As well, we retry any aux transaction on any error 32
times. 7 * 32 = 224, which means this loop causes us to retry grabbing
the dpcd 224 times. This is definitely far more then we actually need to
do.

alloc_workqueue replaces deprecated create_singlethread_workqueue().
Each hardware CRTC has a single flip work queue.
When a radeon_flip_work_func item is queued, it needs to be executed
ASAP because even a slight delay may cause the flip to be delayed by
one refresh cycle.
Hence, a dedicated workqueue with WQ_HIGHPRI set, has been used here
since a delay can cause the outcome to miss the refresh cycle.
Since there are only a fixed number of work items, explicit concurrency
limit is unnecessary here.
