wistron_btns: Generic keymap

It turns out that the mapping of the wistron code is always the same, the
main difference being some keys which may not exist and leds which might not be
present. Therefore it's possible to write a generic keymap which would allow
the use of an unknown keyboard with little drawbacks. The user can select it
specifying the parameter "keymap=generic".
