Subject: [PATCH] input - input.h: Add a new switch event

One of Wacom's pen and touch capable models added a switch for
users to turn on/off touch events. We need to report the state of
this switch to userland. But, there is no existing switch event
defined for this purpose. Luckily enough, there is a room for a
new switch event.
