iio: distance: srf08: add driver ABI documentation
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
