So this one is special, since it tries to prevent races when userspace
crashes simply by disabling the vblank machinery. Well except that imx
always has vblanks enabled, and the disable_vblank hook actually just
tries to cancel a pending pageflip. Without any locking whatsoever. Of
course this is wrong, since it'll result in the hw not actually
displaying what drm thinks is the current frontbuffer.

Well since the core takes care of the disappearing DRM fd now. So we
can nuke all this confused code without ill side-effects.

Someone else needs to audit the locking for ->newfb and
->page_flip_event and fix it up. Common approach is to reuse
dev->event_lock for this.

The core code now takes care of unlinking drm_events from the file in
a generic way, so this code isn't needed any more.

For those wondering where the drm_vblank_put went to: With the new
logic events only get unlinked, but still exist. Hence any resources
(like vblank counters) don't need to be released since the event user
will still process the event normally. In this case this is the
callsites of send_vblank_event, which of course already have a
drm_vblank_put.

There's really no reason to not do so, instead of replicating this
for every use-case and every driver. Now we can't just nuke the events,
since that would still mean that all drm_event users would need to know
when that has happened, since calling e.g. drm_send_event isn't allowed
any more. Instead just unlink them from the file, and detect this case
and handle it appropriately in all functions.

  ...

The drm_fbdev_cma_init function always calls the
drm_helper_disable_unused_functions. Since it's part of the usual probe
process, all the drivers using that helper will end up having their encoder
and CRTC disable functions called at probe if their device has not been
reported as enabled.

This could be fixed by reading out from the registers the current state of
the device if it is enabled, but even that will not handle the case where
the device is actually disabled.

Moreover, the drivers using the atomic modesetting expect that their enable
and disable callback to be called when the device is already enabled or
disabled (respectively).

We can however fix this issue by moving the call to
drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the
drivers needing it (all the drivers calling drm_fbdev_cma_init and not
using the atomic modesetting) explicitly call it.

When the framebuffer is a vmwgfx dma buffer and a proxy surface is
created, the vmw_kms_update_proxy() function requires that the proxy
surface width and the framebuffer pitch are compatible, otherwise
display corruption occurs as seen in gnome-shell/native with software
3D. Since the framebuffer pitch is determined by user-space, allocate
a proxy surface the width of which is based on the framebuffer pitch
rather than on the framebuffer width.
