PATCH 1/1 libata: fix ata_piix on ICH6R in RAID mode

Jeff,

Here is the cleaned up patch (as you suggested) that enables ata_piix to work in RAID mode on ICH6R. I tested it and it seems to behave correctly
in all the modes---sees all 4 disks in IDE and RAID modes, doesn't see any in Compatibility mode (which is right, because only two are available and the regular IDE driver has picked them up already).
