Abner Chang 2846c19da9 RedfishPkg/RedfishHostInterface: Platform Redfish HI notification
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.
