USB: add USB_DEVICE_INTERFACE_CLASS macro
commit 17b72feb2be14e6d37023267dc0e199e8e0e3fdc upstream.
Matching on device and interface class with with unspecified
subclass and protocol is sometimes useful. This is slightly
different from USB_DEVICE_AND_INTERFACE_INFO which requires
the full interface class/subclass/protocol triplet.
