Bus Specific Driver Override Protocol
This protocol matches one or more drivers to a controller. This protocol is
produced by a bus driver, and it is installed on the child handles of buses
that require a bus specific algorithm for matching drivers to controllers.
This protocol is used by the EFI_BOOT_SERVICES.ConnectController() boot
service to select the best driver for a controller. All of the drivers
returned by this protocol have a higher precedence than drivers found in
the general EFI Driver Binding search algorithm, but a lower precedence
than those drivers returned by the EFI Platform Driver Override Protocol.
If more than one driver image handle is returned by this protocol, then the
drivers image handles are returned in order from highest precedence to
lowest precedence.
