mac_newworld: move wiring of macio IRQs to macio_newworld_realize()

Since the macio device has a link to the PIC device, we can now wire up the IRQs directly via qdev GPIOs rather than having to use an intermediate array. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
