mac_newworld: use object link to pass OpenPIC object to macio

Browse Source 
Also switch macio_newworld_realize() over to use it rather than using the pic_mem
memory region directly.

Now that both Old World and New World macio devices no longer make use of the
pic_mem memory region directly, we can remove it.
