Hi,

here is one of the rough edges I was talking about earlier.

This function is no longer used outside the st_sensors core module, so there is
no need to export it anymore. In fact it is only used in
st_sensors_sysfs_sampling_frequency_avail, which itself is not more than the
call to st_sensors_get_sampling_frequency_avl, so I'd just move the contents of
st_sensors_get_sampling_frequency_avl to st_sensors_sysfs_sampling_frequency_avail.

Similar here.
