In the future, we'd like to have different HID devices on different endpoints (keyboard, trackpad, etc.), so we'd like to separate the keyboard handling. For other chip implementing usb_hid.c (namely, chip/g), we, for now just rename the config option and endpoint/interface definitions. Making the code more generic can be done at a later stage.
