[PATCH 1/3 v2] input : wacom - Add serial number for Graphire4 and old Bamboo

With the removal of BTN_TOOL_FINGER for tablet buttons and
expresskeys, serial number is needed to distingush if the
events were from a regular tool (stylus, eraser, or mouse)
or the attribures (buttons, strips, or wheels) on the tablet
since there are overlapped events between the tools and the
tablet attributes.

This patch I believe will even work in isolation of others in series
and will fix some pad button issues reported by various graphire
users.
