[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>

[SPARC64]: of_device layer IRQ resolution Do IRQ determination generically by parsing the PROM properties, and using IRQ controller drivers for final resolution. One immediate positive effect is that all of the IRQ frobbing in the EBUS, ISA, and PCI controller layers has been eliminated. We just look up the of_device and use the properly computed value. The PCI controller irq_build() routines are gone and no longer used. Unfortunately sbus_build_irq() has to remain as there is a direct reference to this in the sunzilog driver. That can be killed off once the sparc32 side of this is written and the sunzilog driver is transformed into an "of" bus driver. Signed-off-by: David S. Miller <davem@davemloft.net>
