au0828: provide module option to disable USB speed check
From: Devin Heitmueller <dheitmueller@kernellabs.com>
Add an au0828 module option that allows a user to override the USB speed check.
Intended for advanced users who understand the consequences of trying to use
the device with a 12Mbps bus.
Priority: normal
