Subject: [PATCH] platform/x86: touchscreen_dmi: Add info for the "Connect Tablet 9" tablet

Add touchscreen info for the "Connect Tablet 9" tablet. This appears to be
a variant of the same hardware as the ITworks TW891 tablet, but it needs
different firmware for the touchscreen to fonction properly.
