Ah, that explains what it is. Sorry, use in_proximitiy0_sampling_frequency to provide equivalent
control please. Might be a pain here, but this interface will just provide the same info as the existing
one in a different form. Note that sampling_frequency is documented as a general one, but can
be extended to individual channels.

Actually add it to the iio-core as an element in the info_mask as I doubt this will be the last time
we see this control. This will need to be a precursor patch to the driver obviously.

IIO_CHAN_INFO_SAMP_FREQ and the relevant shared and separate macros need to go in
iio.h + the text entry in industrialio-core.c

If you like I can do this but it'll be quicker if you do :)
