iio: gyro: adis16260: replace mlock with ADIS lib's state_lock
This change uses the ADIS library's state_lock to protect the state of the `max_speed_hz` change that is done during the set of the sampling frequency. Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
