hwmon: (w83627hf) Document W83627THF voltage pin mapping

I had to look it up for one user, so we might as well store it in the
driver documentation.

 The above sequence assumes a Super-I/O config space at 0x2e/0x2f, but
 0x4e/0x4f is also possible.

+Voltage pin mapping
+-------------------
+
+Here is a summary of the voltage pin mapping for the W83627THF. This
+can be useful to convert data provided by board manufacturers into
+working libsensors configuration statements.

+For other supported devices, you'll have to take the hard path and
+look up the information in the datasheet yourself (and then add it
+to this document please.)
