[OpenBIOS] [PATCH 1/10] Dummy get-key-map in keyboard device package

[William Hahne]

"get-key-map" is a Forth word that provides a map of all the keys currently
pressed on the keyboard. Since it is only used by BootX to determine if one
of the shortcuts for verbose or single user mode is pressed. It is a waste
of time to provide a full implementation. This just hands out a dummy key
map which specifies verbose mode.
