msm: ultrasound: Add Sync Gesture data format

Sync gesture is a new service implemented
in the ultrasound team in the kernel, user space
and the DSP layers.
This service detects user gestures and turns
them into android keyboard keys.

The sync gesture service data format should be
supported in the ultrasound related definitions
in the kernel to be able to use the suitable
services in the DSP.
