This compatible doesn't look specific enough. It should at least have
a vendor prefix.

Typically, we've been doing these external bust controller type
gadgets with address-cells = <2>, the first cell explicitly encoding
the chipselect. This gets us closer to the ideal of the device tree
encoding only hardware information, not how the bridge controller is
configured (although "ranges" will still have to contain configuration
dependent information).
