[coreboot] drivers/generic/ioapic enable_dev not called

[Alex G.]

For some reason, it seems that coreboot cannot find devices at those
devfn. Normally, I'd say "are you sure you aren't setting/unsetting a
bit that disables those devices" but there are just too many leftover
devices.

As a first step, pci_scan_get_dev() seems to be the offender. I would
put a printk to get both the argument devfn, and
(*list)->path.pci.devfn, and try to figure out why the "offending"
devices are not located. This should at least shed some light on where
to look next.
