[OpenBIOS] [PATCH] usbhid: Implement get-key-map method

[BALATON Zoltan]

Mac OS X calls it during boot. This gets rid of an error saying
"call-method slw_update_keymap failed with error ffffffdf" but
otherwise does not seem to matter. It's probably used for getting the
pressed keys that can change some boot actions like enable verbose
mode with Cmd-V.
