	  Enable automatic acknowledge of slave basic configuration been
	  completed by sending a virtual wire message to the eSPI master.
	  This depends on SPI boot configuration. It could be either very
	  early in the flow after the VW channel is configured. Or it could be
	  until flash channel is configured.
