USB: introduce usb_interface/usb_configuration structs
On little endian systems like ARM the le16_to_cpus() macro
is a no op, defined as:
#define le16_to_cpus __le16_to_cpus
#define __le16_to_cpus(x) do {} while (0)
So struct usb_configuration field misuse was discovered
on big-endian MIPS machine.
