sparc: Add sparc support for platform_get_irq()
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.
