Subject: input: add a DMI table for the i8042.reset option; make MSI Wind U-100 work

There are several DMI tables in the i8042 (keyboard) driver already,
but not one for the i8042.reset option. This patch adds such an option
(which also sets the nonfatal flag so that if the reset fails, the keyboard
still works).

Two users for this table are added as well, the MSI Wind U-100 and the
LG X110. The MSI Wind also needs to be in the "don't trust the pnp data"
for the touchpad to work on my machine.
