Input: wacom - add 0xE5 (MT device) support
Main part of patch is adding support for a new Wacom MT touch
packet and labels these devices using MTSCREEN type.
Other items of interest:
Delete some duplicate code in HID parsing for Y info since
its already done in X path.
In wacom_query_tablet_data(), only invoke the set report
that requests tablets to send Wacom Touch packets for
Finger interfaces. Mostly, this is to make code intent clear.
