hwmon: (f71882fg) Prepare for adding F8000 support
This patch is a preparation patch for adding F8000 support to the f71882fg driver. If you look at the register addresses and esp, the bits used for the temperature channels, then you will notice that it appears that they start at 1 in a system meant to start at 0. As the F8000 actually uses the 0 addresses and bits, this patch changes the f71882fg driver to take 4 temperatures numbered 0-3 in to account, using 1-3 in this new scheme for the temperatures actually present in the F718x2FG.
