iio:adxl372: Add sampling frequency support

Browse source

This patch adds the option for the user to select the sampling frequency.
Also, the user can read the available frequencies and read the currently
set frequency via the read_raw function. The frequency can be set via the
write_raw function.

When the frequency is set, the bandwidth is also checked and ensured
that it is constrained to at most half of the sampling frequency. Also, the
activity and inactivity timers have to be updated because they depend on
the selected ODR.
