USB: ohci: quirk AMD prefetch for USB 1.1 ISO transfer

commit a1f17a872bc7b1cb7efdd5486a2963e88a536e61 upstream.

The following patch in the driver is required to avoid USB 1.1 device
failures that may occur due to requests from USB OHCI controllers may
be overwritten if the latency for any pending request by the USB
controller is very long (in the range of milliseconds).
