Log:
macio: switch over to use 2 ata-3 ide controllers

This better matches real device trees and fixes Darwin/OS X boot from CDROM
under the QEMU mac99 machine (it seems that IOKit will only detect macio IDE
devices connected to an ata-3 ide controller rather than the previous ata-4
ide controller).
