touch devices: Disable touch on softlock.
Target that have a touchpad/touchscreen should disable it while being locked (In order to avoid LCD to drain battery power due to "key locked" constant reporting messages. If they a have a keylock button this was already handled at driver level. If not (e.g. fuze+), they will have to implement a switch at driver level that action.c can operate on softlock. This patch does the following for any target having a touchpad or a touchscreen and no HAS_BUTTON_HOLD (ie any softlock target) 1) it implements the code to call button_enable_touch(bool en) in action.c. 2) button_enable_touch is implemented in button.c and call either touchpad_enable or touchscreen_enable 3) those two function are implemented respectively in touchscreen.c and a new touchpad.c file. They provide a generic way to silents touch's device and call a function at driver level where target specific code can be implemented if possible/needed (for power saving for instance). Those function name are touchpad_enable_device and touchscreen_enable_device 4) we implement an empty function at driver level of targets that need it to have them still being able to compiled.
