hwmon-vid: Fix AMD K8 VID decoding

Not all AMD K8 have 6 VID pins, contrary to what was assumed in
commit 116d0486

. This commit broke
support of older CPU models which have only 5 VID pins:
http://bugzilla.kernel.org/show_bug.cgi?id=11329

We need two entries in the hwmon-vid table, one for 5-bit VID models
(K8 revision <= E) and one for 6-bit VID models (K8 revision >= F).
This fixes bug #11329.
