superio/ite: Fix incorrect warnings

Fix warning for disabled thermal inputs.

Fix warning for PECI thermal inputs if one was set up previously.
Depending on the mb, the superio will not go through power-on reset and
retain its registers. Do not trigger a warning if the current register
value aligns with the desired value. Don't return early if some input is
already configured for PECI, simply overwrite the configuration.

Both warnings were observed while porting the "HP Pro 3500 Series" mb.
