The _DDN is a "DOS device name", and the _UID is a "logical device ID

ignores them. But maybe we could change PNPACPI to sort by them if
they are present. I'll think about this a bit.

this happen with muliti peer root buses too.
some DSDT put bus 0x80 before 0x0. So the bus 0x80 is scanned by the
kernel at first. so some device such as nic number is reversed too...

need to make some change to acpica...
