PCI: Mark Atheros AR9580 to avoid bus reset
commit 8e2e03179923479ca0c0b6fdc7c93ecf89bce7a8 upstream.
Similar to the AR93xx and the AR94xx series, the AR95xx also have the same
quirk for the Bus Reset. It will lead to instant system reset if the
device is assigned via VFIO to a KVM VM. I've been able reproduce this
behavior with a MikroTik R11e-2HnD.
