Series macio: remove legacy macio_init() function | expand

Commit Message

Mark Cave-Ayland Feb. 20, 2018, 6:41 p.m. UTC
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.
