[SPARC64]: Add of_device layer and make ebus/isa use it.
Sparcspkr and power drivers are converted, to make sure it works. Eventually the SBUS device layer will use this as a sub-class. I really cannot cut loose on that bit until sparc32 is given the same infrastructure. Signed-off-by: David S. Miller <davem@davemloft.net>
