superio/ite: allow 24 MHz clock for external sensor interface
The interface selection register of the environment controller (EC) gives the choice between "Internal generated 32 MHz" and "24 MHz" for the "SST/PECI Host Controller Clock Selection". Previously the chip was always configured for the 32 MHz clock. Add an option that can be set from devicetree.cb to allow using the 24 MHz clock. Without this setting the automatic fan control on an Acer Aspire M3800 was slow to respond to temperature changes.
