Input: synaptics_i2c_rmi: Send new multi touch events
Send both fingers using the new multitouch protocol in addition to
the old single finger event and second finger ABS_HAT* hack.
The new protocol does not specify how to report up events. To make
sure the user-space frameworks can generate up events, we send at
least one event where ABS_MT_TOUCH_MAJOR is zero before we stop
sending events for a finger.
