Instead of checking machine type in the function,
use machine_device_initcall().

This machine matches two compatibles and sets .pci_irq_fixup
on one of them.
Split it into two machines, then the probe function can be dropped.

Use ppc_md_progress() instead.
Note that checkpatch complains about using function names,
but this is not a function taking format strings, so we
leave the function names for now.

Use the new 'compatible' property for simple cases.
checkpatch complains about the new compatible being undocumented
but in reality nothing is new so just ignore it for the time
being.
