intel/apollolake: Add parameter to enable VTD in devicetree
The FSP has a parameter to enable or disable the VTD feature (Intel's Virtualization Technology for Directed I/O). In current header files for FSP-S (Apollo Lake and Gemini Lake) this parameter is set to disabled per default. Therefore, if the FSP was not modified via BCT, this feature is most likely disabled on all mainboards. Add a chip parameter so that VTD can be enabled on mainboard level in devicetree and therefore this feature can be activated if needed.
