Quirking the following AMI USB device with ALWAYS_POLL fixes an AMI
virtual keyboard and mouse from not responding and timing out when
it is attached to a ppc64el Power 8 system and when we have some
rapid open/closes on the mouse device.

 usb 1-3: new high-speed USB device number 2 using xhci_hcd
 usb 1-3: New USB device found, idVendor=046b, idProduct=ff01
 usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
 usb 1-3: Product: Virtual Hub
 usb 1-3: Manufacturer: American Megatrends Inc.
 usb 1-3: SerialNumber: serial
 usb 1-3.3: new high-speed USB device number 3 using xhci_hcd
 usb 1-3.3: New USB device found, idVendor=046b, idProduct=ff31
 usb 1-3.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3
 usb 1-3.3: Product: Virtual HardDisk Device
 usb 1-3.3: Manufacturer: American Megatrends Inc.
 usb 1-3.4: new low-speed USB device number 4 using xhci_hcd
 usb 1-3.4: New USB device found, idVendor=046b, idProduct=ff10
 usb 1-3.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
 usb 1-3.4: Product: Virtual Keyboard and Mouse
 usb 1-3.4: Manufacturer: American Megatrends Inc.

With the quirk I have not been able to trigger the issue with
half an hour of saturation soak testing.
