The "Ibex support" in question only refers to the SMBus controller, not
to sensors directly.

We have never heard of this chip ID. This must be a brand new
Winbond/Nuvoton Super-I/O chip. Please look at the motherboard, search
for the Super-I/O and report the top marking. You may also find its
name in the user manual (but the top marking is even more reliable.)
