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 unknown keyboard. The user can select it specifying the parameter
"keymap=generic".
