Documentation: hwmon: Add descriptions for ina2xx sysfs entries 



There are a few sysfs entries being exposed to user space by the
ina2xx hwmon driver while not getting explicitly documented. So
this patch just adds a description section for them.

don't touch the conversion times and only modify the number of averages. The

lower limit of the update_interval is 2 ms, the upper limit is 2253 ms.

The actual programmed interval may vary from the desired value.



General sysfs entries

-------------



in0_input		Shunt voltage(mV) channel

in1_input		Bus voltage(mV) channel

curr1_input		Current(mA) measurement channel

power1_input		Power(uW) measurement channel

shunt_resistor		Shunt resistance(uOhm) channel



Sysfs entries for ina226, ina230 and ina231 only

-------------



update_interval		data conversion time; affects number of samples used

			to average results for shunt and bus voltages.
