[POWERPC] Compare irq numbers with NO_IRQ not IRQ_NONE
There is a thinko in the irq code, it uses IRQ_NONE to indicate no irq,
whereas it should be using NO_IRQ. IRQ_NONE is returned from irq
handlers to say "not handled".
As it happens they currently have the same value (0), so this is just for
future proof-ness.
