Ata_piix's Kconfig entry still refers only to ICH5, while it supports ICH6
through 8. This creates confusion with people who are looking to see
if their newer SATA enabled motherboards are supported. The
following patch makes this clear.

Some SATA controllers embedded in ATI IXPs seem to have broken
SATA_IRQ bit in their bmdma2 registers which is always stuck at 1.
This makes the driver believe that there has been a hotplug event and
freeze the port whenever there's an interrupt thus failing all
commands.

This patch disables SATA_IRQ for those controllers.
