hwmon: (abituguru3) Support multiple DMI strings per chip ID
Most known Abit motherboards have unique uguru chip IDs. However,
some "refresh" boards keep the same chip ID but have a different
DMI string. As our DMI board string matching is (necessarily)
strict, some boards were failing DMI detection, and as the old
probe method was also failing, the driver would not load.
The only known boards affected by this problem are the IP35 Pro XE
(vs IP35 Pro) and the AB9 Pro (vs AB9). Is it not sufficient to
relax the match criteria, as some boards (e.g. the AB9 Quad GT)
have different uguru chip IDs.
This patch replaces the dmi_name string with a NULL terminated
array of strings to be matched per uguru chip ID. It has been
compile and runtime tested (thanks Rune).
