On a real G3 Beige the secondary IDE bus lives on the mac-io chip, not
on some random PCI device. Move it there to become more compatible.
While at it, also clean up the IDE channel connection logic.

Mac OS X's debugging serial driver accesses the ESCC through a different
register layout, called "escc-legacy". This layout differs from the normal
escc register layout purely by the location of the respective registers.
This patch adds a memory alias region that takes normal escc registers and
maps them into the escc-legacy register space.
With this patch applied, a Mac OS X guest successfully emits debug output
on the serial port when run with debug parameters set, for example by running:
$ qemu-system-ppc -prom-env -'boot-args=-v debug=0x8 io=0xff serial=0x3' \
-cdrom 10.4.iso -boot d
