tablet: explicitly ignore ABS_THROTTLE, ABS_RX, ABS_RY, and ABS_RZ

Browse source 
ABS_THROTTLE:
	Tablets still advertise this axis but the mouse itself isn't available
	anymore. The Pad sends the second wheel as ABS_THROTTLE but that's a
	task for the buttonset interface.  Explanation of what the throttle
	did on page
	http://101.wacom.com/productsupport/manual/Intuos2UsersManual.pdf

ABS_RX/ABS_RY:
	These only happen on the Intuos3 device and only on the Pad device
	(kernel >= 3.17)

ABS_RZ:
	The 4D mouse for the Intuos2, obsolete.

No functional changes, this is to clarify why we're only handling a subset of
codes.
