There are differences between the ICH8 and ICH9 SATA controller.  For
example, the PCS register now has port present bits that used to be
reserved in ICH8.  I'm not sure how or if these could be used in
ata_piix.

Separating ich9 out from ich8 isn't difficult. Let's do that when there is need. ata_piix always has been using the same entry if there is no code difference and I don't see any reason to depart from that with ich9.

Thanks.
