Actually a grep of "usb-ehci" turns up the ehci-ppc-of driver which I somehow 
missed. This driver works and uses .compatible = "usb-ehci" so I can use that 
instead if that is preferable?

However it is basically the same as the ehci-platform driver so I guess at 
some point the two should be merged...
