Setup the touchpads to have two modes - stylus and button - and set them in button mode by default.

in button mode the touchpad is split into a 3x3 grid for 9 seperate buttons which can be used by the action system like real buttons.
Unify the keymap file for the touchpads in button mode. the target keymap file only needs to worry about real buttons.
(As these ports mature each screen will need to be fixed seperatly to be able to use stylus mode (the lists can already but don't change mode just yet.)

+   These tables are only used for the touchpad buttons, so at the end of each
+   CONTEXT_CUSTOM2 is OR'ed with the context and then sent to target_get_context_mapping()
+   (NOTE: CONTEXT_CUSTOM2 will be stripped before being sent to make it easier.)
+   In the target keymap, remember to |CONTEXT_CUSTOM2 in the  LAST_ITEM_IN_LIST__NEXTLIST() macro
+   to speed it up a tiny bit... if you dont it will go through these tables first before going
+   back to the target file.
