[SPARC]: Beginnings of generic of_device framework.
The idea is to fully construct the device register and interrupt values into these of_device objects, and convert all of SBUS, EBUS, ISA drivers to use this new stuff. Much ideas and code taken from Ben H.'s powerpc work. Signed-off-by: David S. Miller <davem@davemloft.net>
