iio: imu: st_lsm6dsx: add read_fifo callback to fifo_ops
Remove static qualifier from st_lsm6dsx_read_fifo definition and
introduce read_fifo function pointer in fifo_ops data structure
in order to run the proper read_fifo routine since other compliant
devices will use a different FIFO queueing scheme.
