sata_mv: enable async_notify for 60x1 Rev.C0 and higher
The early chipsets cannot safely handle Async Notification (AN), but 6041/6081 chip revision "C0" (and newer) can handle it. So allow AN for "C0" and higher. This enables use of hotplug on PMP ports for the 6041/6081 PCI Rev.9 chips. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
