Subject: [PATCH] input: touchscreen: nova_0flash_mmi: Rework gesture node

Make gesture_show actually report the current enabled gestures and move
away from supported_gesture_type since that is just hardcoded in dts.

Rewrite gesture_store so that we are can toggle dt2w from userspace
with a simple 0/1 write.
