mb/google/hatch/var/kohaku: Add Samsung S-pen driver support

Browse source 
Modify the Wacom digitizer HID to support the Samsung S-pen. This allows
a different driver to attach under Windows, which adds support for the
side buttons as eraser function and air command.

TEST=build/boot kahaku, verify S-pen works under Windows/Linux
