Input: wacom - fix touch parsing on newer Bamboos
Bamboos with Product ID's > 0xD4 return values unrelated to pressure
in touch 1 pressure field. They also report 2nd touch X/Y values
shifted down 1 byte (where pressure was). This results in jumpy
1 finger touch and totally invalid 2nd finger data.
For touch detection, switch to a Touch Present single bit that
all versions of Bamboo support.
For touch 2 offset, calculate offset based on a bit that is set
different between the two packet layouts.
Since touch pressure reports were removed from driver, there was
no need to be reading pressure any more.
