------------------------------------------------------
Subject: libata: PIIX3 support
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
This I believe completes the PIIX range of support for libata
This adds the table entries needed for the PIIX3, both a new PCI identifier
and a new mode list. It also fixes an erroneous access to PCI
configuration 0x48 on non UDMA capable chips.
