input: touchscreen: sec_ts: export to the touch_offload driver
The touch_offload driver makes it possible for the sec_ts driver to
export heatmap and coordinate data to a user space consumer. The sec_ts
driver is responsible for initializing the touch_offload driver with
information about its supported capabilities. Then, as touch events
occur, the sec_ts driver must capture required heatmap/coordinate
frames, load it into buffers provided by the touch_offload driver, and
submit the buffers back to the touch_offload driver. Finally, the sec_ts
driver must report touch input events through a callback provided to
touch_offload.
