powerpc: Remove i8259 irq_host_ops->unmap
It was never called because the host is always IRQ_HOST_MAP_LEGACY. And what it purported to do was mask the interrupt (which will already have happend if we shutdown the interrupt), then synchronise_irq and clear the chip pointer, both of which will have been be done by the caller were we to call unmap on a legacy irq.
