commit 6afb7e26978da5e86e57e540fdce65c8b04f398a upstream.
When using PCI passthrough with this device, the host machine locks up
completely when starting the VM, requiring a hard reboot. Add a quirk to
avoid bus resets on this device.
Fixes: c3e59ee4e766 ("PCI: Mark Atheros AR93xx to avoid bus reset")
