/**\r
  Register the callback function for ReportStatusCode() notification.\r
\r
  When this function is called the function pointer is added to an internal list and any future calls to\r
  ReportStatusCode() will be forwarded to the Callback function. During the bootservices,\r
  this is the callback for which this service can be invoked. The report status code router\r
  will create an event such that the callback function is only invoked at the TPL for which it was\r
  registered. The entity that registers for the callback should also register for an event upon\r
  generation of exit boot services and invoke the unregister service.\r
  If the handler does not have a TPL dependency, it should register for a callback at TPL high. The\r
  router infrastructure will support making callbacks at runtime, but the caller for runtime invocation\r
  must meet the following criteria:\r
  1. must be a runtime driver type so that its memory is not reclaimed\r
  2. not unregister at exit boot services so that the router will still have its callback address\r
  3. the caller must be self-contained (eg. Not call out into any boot-service interfaces) and be\r
  runtime safe, in general.\r
