iio: adc: ad799x: do not use internal iio_dev lock
'mlock' was being grabbed when setting the device frequency. In order to
not introduce any functional change a new lock is added. With that in
mind, the lock also needs to be grabbed in the places where 'mlock' is
since it was also being used to protect st->config against the current
device state.
On the other places the lock was being used, we can just drop
it since we are only doing one i2c bus read/write which is already
safe.
While at it, properly include "mutex.h" for mutex related APIs.
