This adds sparc support for platform_get_irq that in the normal case use
platform_get_resource() to get an irq. This standard approach fails for sparc as
there are no resources of type IORESOURCE_IRQ for irqs for sparc.

Cross platform drivers can then use this standard platform function and work on
sparc instead of having to have a special case for sparc.

Sorry, subject line incorrect. New version sent.
