The SMM Exit Boot Service protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_GROUP_EXIT_BOOT_SERVICES
to notify SMM driver that system enter exit boot services.
The SMM Legacy Boot protocol is to be published by the SMM
Foundation code to associate with EFI_EVENT_LEGACY_BOOT_GUID
to notify SMM driver that system enter legacy boot.
