Update the ad4695 documentation to say that buffered reads are
supported. Since there are 4 possible modes of reading conversion data,
it is useful to know which one is actually being used, namely the
advanced sequencer mode.

The AD7380 family has some compatible single-ended chips: AD7386/7/8(-4).
These single-ended chips have a 2:1 multiplexer in front of each ADC.
They also include additional configuration registers that allow for either
manual selection or automatic switching (sequencer mode), of the
multiplexer inputs. Add a section to describe this.

Allow setting frequency below 1Hz or sub 1Hz precision.
Useful for slow sensors like ALS.
Test frequency is set properly:

cd /sys/bus/iio/devices/triggerX ;
for i in 1 .1 .01 .001 ; do

- 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.
