iio: Add FIFO event for LSM6DSR sensor HUB

Browse Source 
Add FIFO event type:
* IIO_EV_TYPE_FIFO_FLUSH

This change also adds FIFO event directions:
* IIO_EV_DIR_FIFO_EMPTY (indicates the FIFO is empty)
* IIO_EV_DIR_FIFO_DATA (indicates the FIFO is not empty)

A FIFO flush event is triggered after the HW FIFO is flushed,
and indicates that whether the HW FIFO is empty or not.
