/** @file
  Provides services to log the SMI handler registration.

  This API provides services for the SMM Child Dispatch Protocols provider,
  to register SMI handler information to SmmCore.

  NOTE:
  There is no need to update the consumers of SMST->SmiHandlerRegister() or
  the consumers of SMM Child Dispatch Protocols.
  The SmmCore (who produces SMST) should have ability to register such
  information directly.
  The SmmChildDispatcher (who produces SMM Child Dispatch Protocols) should
  be responsible to call the services to register information to SMM Core.

                         must match the one defined for SmmChildDispatch protocol.
