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

+Date:		January 2017
+KernelVersion:	4.11
+Contact:	linux-iio-u79uwXL29TY76Z2rM5mHXA@public.gmane.org
+Description:
+                Show or set the maximum range between the sensor and the
+		first object echoed in meters. Default value is 6.020.
+		This setting limits the time the driver is waiting for a
+		echo.
+		Showing the range of available values is represented as the
+		minimum value, the step and the maximum value, all enclosed
+		in square brackets.
+		Example:
+		[0.043 0.043 11.008]
