soc/intel/skylake: Enable CIO depending on devicetree configuration

Currently, CIO gets enabled by the option Cio2Enable, but this
duplicates the devicetree on/off options. Therefore, depend on
the devicetree for the enablement of the CIO controller.

All corresponding mainboards were checked if the devicetree
configuration matches the Cio2Enable setting, and missing entries
were added.
