soc/intel/skylake: Enable SA IMGU depending on devicetree configuration

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

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