sparc32: introduce build_device_irq
build_device_irq() is used to encapsulate the plaform specific details when we build an irq. For now the default is a simple 1:1 but sun4d differs. This patch refactors functionality - but does not change the existing functionality. Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S. Miller <davem@davemloft.net>
