This control on the gain of a measurement used for time of flight sensing
is standard but the expected values for different enviroments may not be.
As we cannot have the same ABI element documented in two files, add a
generic version to sysfs-bus-iio-proximity and a note on the expected
value vs measuring environment for the as3935.

On those three files, the ABI representation described at
README are violated.
- at sysfs-bus-iio-proximity-as3935:
a ':' character is missing after "What"
- at sysfs-class-devfreq:
there's a typo at Description
- at sysfs-class-cxl, it is using the ":" character at a
file preamble, causing it to be misinterpreted as a
tag.
- On the other files, instead of "What", they use "Where".

Add sysfs-bus-iio-distance-srf08 for individual attributes of the driver,
especially:
- sensitivity which the device documentation calls gain for amplifying the
signal
- max_range for limiting the maximum distance for expected echos and
therefore limiting the time waiting for telegrams
