This change removes the use of indio_dev's mlock in favor using the state
lock from the ADIS library.
The set_freq() & get_freq() hooks are unlocked, so they require specific
locking. That is because in some cases the get_freq() hook is used in
combination with adis16400_set_filter().
In cases where only one read/write is done, the functions that hold the
state lock are used.
