This patch adds protocol definitions (and the corresponding global 

EFI_GUID instances) for EFI_PLATFORM_DRIVER_OVERRIDE_PROTOCOL,
EFI_DRIVER_FAMILY_OVERRIDE_PROTOCOL, and
EFI_BUS_SPECIFIC_DRIVER_OVERRIDE_PROTOCOL, used in the driver
binding search procedure to select which driver to connect when
multiple drivers' Supported() functions indicate support for
the same controller.
