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

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

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