[lm-sensors] W83627DHG support patch

[lm-sensors] W83627DHG support patch

[Con Kolivas]

Hi all

Browsing the past archives I saw that the W83627DHG chip was a lot like the 
w83627ehf driver and support shouldn't be too hard to add. So I probed my own 
hardware to see what it returned and added a small patch to try to make it 
work. The output of  sensors after that seems accurate apart from AUX Temp 
which seems to jump around a bit. The cpu and system temperature, fan speeds 
and voltages that I have all seem pretty close too.

Here is a patch that I created for the 2.6.19 kernel that gave me the output I 
required. I doubt very much that this is the correct and final approach so it
may blow up your machine etc etc so for those who are desparate and want to
try it all the usual warnings apply and so on... :D
