help
Enable automatic acknowledgment from eSPI slave towards eSPI host
whenever it receives suspend or reset warning.
If this is disabled, it means the app wants to be give the opportunity
to prepare for either HOST suspend or reset.

Enable automatic acknowledgment from 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.
