Eric Piel 6480e2a275 Input: wistron - add acerhk laptop database 
Acerhk supports already a lot of laptops. Lets import its database so
that everyone can benefit of the work of Olaf Tauber. Only the "tm_new"
laptops were imported. "tm_old" laptops could be possible but requires
more testing and probably only few laptops are still alive. "dritek"
laptops should probably be imported into a different driver. Also compress
the keymaps by fitting each entry on an int. Most of the dmi matching was
written based on google searches, so it's rather prone to errors. That's
why I'm asking people to confirm it works.

Support to generate switch input events was added as some laptops indicate
lid open/close through this interface.

This adds the following hardware:
