soc/intel/skylake: indicate voltage margining enabled/disabled
Support for voltage margining is dependent on the platform.
Enabling voltage margining puts additional constraints for
the SLP_S0# to be asserted and hence moving to S0ix state.
If the platform PMIC/VR supports PCH voltage reduction,
voltage marigining can be enabled.
Use the UPD provided by FSP to enable/disable voltage margining.
