This work struct will be used to schedule a uevent on a separate
thread. This will be scheduled after a link train failure during modeset
to indicate a modeset retry request. It will get executed after the
current modeset is complete and all locks are released. This was
required to avoid deadlock.

* Create a generic work func not i915 specific (Daniel Vetter)
