For some use cases, Redfish host interface table relies on the certain EFI protocols installation at the driver connection. Redfish host interface DXE driver is not able to build the SMBIOS type 42h record at driver entry point. This patch adds the mechanism in Redfish host interface DXE driver to listen to EFI protocol installed by platform library that indicates the necessary information is ready for building SMBIOS 42h record.
