I don't think we should be adding DT nodes for the old, downstream-only
fbdev driver to the upstream tree.  We have nodes already for the open
source driver that directly programs the hardware, which will disable
the firmware's closed-source modesetting interfaces used by bcm2708
fbdev.  For early boot display, the proper solution is simplefb, not a
custom fbdev driver.
