HID: multitouch: Disable touchpad on firmware level while not in use

Browse source

Using the new on_hid_hw_open and on_hid_hw_close functions to disable the
touchpad on firmware level while not being in use.

This safes some battery and triggers touchpad-disabled-leds hardwired to
the touchpads firmware, that exist for example on some TongFang barebones.
