HID: wacom: Move handling of Intuos status packets to seperate function

Browse source 
In addition to the touchswitch state for "Intuos", these packets are
also sent by the Intuos Pro, Intuos5, and last-generation Bamboo
tablets when using a wired connection. They contain, among other
things, information about the optional wireless module and battery
charge state (to be supported in subsuquent patches).
