superio/ite/common: Make PECI a thermal mode

Instead of setting "peci_tmpin" in the devicetree, THERMAL_PECI is now
a mode of TMPIN like THERMAL_RESISTOR and THERMAL_DIODE. Since the logic
to set temperature offsets and limits is in the function that sets
thermal modes, it makes sense to treat PECI as yet another mode.

As of this commit, there are no boards that actually use peci_tmpin from
ite/common. There are three boards that have a similar device tree
option, but those boards use it8772f, which implements all superio
functions on its own.

The first user will probably be Gigabyte GA-Z77-DS3H.
