need help with kern/42758 - correctly initialize W83627HF hwmon

[Michael Stapelberg <michael+netbsd%stapelberg.de@localhost>]

Hi,

Yesterday I debugged why the temperature values seen in envstat on my mainboard
looked very odd (70 degC while the bios hardware monitor shows 40 degC). As I
described in the bugreport, it is a missing initialization.

I also attached a patch to the bugreport, which fixes the problem to me.
However, I am not a NetBSD kernel developer, so the patch very likely needs
some polishing. It would be great if someone could have a look at it so that
it can go into the next NetBSD release.

Best regards,
Michael

PS: kern/42759 is related to this and a rather simple patch - it needs to be
merged before debugging kern/42758 (so that the i2c is accessible on this
board).
