usb: gadget: add RNDIS configfs options for class/subclass/protocol
This adds 3 new options to the RNDIS gadget function configs. It allows overriding the default USB interface class/subclass/protocol. The motivation for this is that if you set the values to "ef" (Misc), "04" (RNDIS), "01" (Ethernet) respectively, then the device will be recognized by the rndiscmp.inf file in Windows Vista and newer and will cause Windows to load the correct RNDIS driver without the need for a custom (signed) .inf file.
