Add RTIO async and RTIO stream functionalities that enables,
among all the other things, the sensor data streaming from FIFO.
RTIO stream is using both SENSOR_TRIG_FIFO_WATERMARK and
SENSOR_TRIG_FIFO_FULL triggers. The decoder currently only supports
following FIFO tags:
- LSM6DSV16X_XL_NC_TAG
- LSM6DSV16X_GY_NC_TAG
- LSM6DSV16X_TEMP_NC_TAG
Following FIFO parameters has to be defined in device tree to
correctly stream sensor data:
- fifo-watermark (defaults to 32)
- accel-fifo-batch-rate (defaults to LSM6DSV16X_DT_XL_NOT_BATCHED)
- gyro-fifo-batch-rate (defaults to LSM6DSV16X_DT_GY_NOT_BATCHED)
- temp-fifo-batch-rate (defaults to LSM6DSV16X_DT_TEMP_NOT_BATCHED)
