drm/nouveau: punt fbcon resume out to a workqueue
Preparation for some runtime pm fixes. Currently we skip over fbcon
suspend/resume in the runtime path, which causes issues on resume if
fbcon tries to write to the framebuffer before the BAR subdev has
been resumed to restore the BAR1 VM setup.
As we might be woken up via a sysfs connector, we are unable to call
fb_set_suspend() in the resume path as it could make its way down to
a modeset and cause all sorts of locking hilarity.
To solve this, we'll just delay the fbcon resume to a workqueue.
