Input: xpad - match xbox 360 devices with interface info
Match Xbox 360 controllers using the interface info, i.e. interface
class 255 (Vendor specific), subclass 93 and protocol 1, instead of
specifying the device ids individually. As the class is vendor-specific,
we have to still match against vendor id as well, though.
