[PATCH] Wistron button support for TravelMate 610

[Eric Piel]

Hello,

Here is a patch adding support to wistron button for Acer TravelMate 
610. This is tested and works fine with the exception of the leds which 
cannot be controlled (yet, that would require writing a led interface 
for them when I've got time ;-) )

I'm sending just this one for now (as I can test it) but if you like it, 
I would like to try to add all the database of keyboards available in 
acerhk (that Olaf has written).

See you,
Eric

TM610 support for wistron_btns.

Adds support for Acer TravelMate 610 to wistron_btns, coming from info 
of acer_hk. All special keys are detected, but the 2 leds are not 
handled (yet).
