Subject: touchscreen_dmi.c Patch for Viglen Connect 10

Hello. 

I previously spoke with you on a touchscreen issue

https://github.com/onitake/gsl-firmware/issues/178

With regard to that, I made a patch for touchscreen_dmi.c. It adds
parameters for the Viglen Connect 10 tablet to get its touchscreen and
home button working.
