Compatible with MSI MAG X670E TOMAHAWK WIFI

Seems to be similar situation as https://github.com/Fred78290/nct6687d/issues/53. There are 4 M.2 slots but only for one of them the temperature is reported (currently unpopulated so unsure if it's working beyond displaying 0).

I can confirm at least CPU voltage, CPU temperatures working properly though. CPU fan values seem to be working fine as well, but the case fans (plugged in as system fans 1 and 2 for back and front) seem to report incorrect values near the minimum. Not sure if that's a sensor or a parsing issue.

Haven't checked for other missing sensors yet.
