Allow setting frequency below 1Hz or sub 1Hz precision.
Useful for slow sensors like ALS.
Test frequency is set properly:
modprobe iio-trig-hrtimer && \
mkdir /sys/kernel/config/iio/triggers/hrtimer/t1 && \
cd /sys/bus/iio/devices/triggerX ;
for i in 1 .1 .01 .001 ; do
echo $i > sampling_frequency
cat sampling_frequency
done

This line is part of the code snippet, so it has to be nested in order
to be rendered correctly.

- Add a SPDX header;
- Adjust document and section titles;
- Use copyright symbol;
- Some whitespace fixes and new line breaks;
- Mark literal blocks as such;
- Add it to filesystems/index.rst.
Also, as this file is alone on its own dir, and it doesn't
seem too likely that other documents will follow it, let's
move it to the filesystems/ root documentation dir.

Rename the iio documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
