soc/intel/common/systemagent: Add Kconfig guard

Looks like selecting SOC_INTEL_COMMON force-sets MMCONF_BASE_ADDR to
some value which can't be overriden outside of soc/intel/common. So
adding a non-SoC platform thats uses code from soc/intel/common is not
possible.

TEST=build test on wip platform
