Now that we wait for DRM panels to be available before registering the
DRM device (returning -EPROBE_DEFER if the panel has not been probed
yet), we no longer need to put the fbdev creation code in
->output_poll_changed().

This removes the 10 secs delay between DRM dev registration and fbdev
creation (polling period = 10 seconds).

+1 Would still be good to eventually resurrect Thierry's deferred fbdev
setup code for other use-cases. But for panels the driver should indeed
not need this.

It should show up in 4.11 (it's already in Linus' tree [1] ;-)).
