The EFI_SMM_CONTROL_PROTOCOL is used by the platform chipset or processor driver. This
protocol is useable both in boot services and runtime. The runtime aspect is so that an
implementation of EFI_SMM_BASE_PROTOCOL.Communicate() can layer upon this service
and provide an SMI callback from a general EFI runtime driver.
