docs: hwmon: Add an index file and rename docs to *.rst
Now that all files were converted to ReST format, rename them
and add an index.

This is equivalent to the current through a 1mOhm -sense resistor. Divide the reported value by the actual sense resistor value -in mOhm to get the actual value. |
