Peter Grehan 8dbee7197d Remove hard-coded knowledge of specific OFW devices. Use bus_generic_probe
and add_child entry point to allow devices to use the identify
method to add themselves if need be (e.g. openpic, syscons).
Export interrupt-controller-add routine for extern int cntlr drivers.
Eliminate recursive OFW device-tree walk and only iterate the
top-level ala sparc64. Allow child devices to set the device
type with write_ivars.

Step 1 of many in removing the hard-dependency on OpenFirmware.
