soc/intel/common: Add option to disable eSPI SMI at runtime
Add an option that will disable eSPI SMI when ACPI mode is enabled, and re-enable eSPI SMI when ACPI mode is disabled. Additionally it ensures eSPI SMI is disabled on the ACPI OS resume path. This allows a mainboard to ensure that the Embedded Controller will not be able to assert SMI at runtime when booted into an ACPI aware operating system. This was tested on a Sarien board with the Wilco EC to ensure that the eSPI SMI enable bit is clear when booted into the OS, and remains clear after resume.
