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

Currently SATA gets enabled by the option EnableSata, but this
duplicates the devicetree on/off options. Therefore use the on/off
options for the enablement of the SATA controller.

I checked all corresponding mainboards if the devicetree configuration
matches the EnableSata setting.
