StatusCode driver is optional dependent on gEfiDataHubProtocolGuid but not always...

/** @file\r
  Status Code Architectural Protocol implementation as defined in Tiano\r
  Architecture Specification.\r
\r
  This driver has limited functionality at runtime and will not log to Data Hub\r
  at runtime.\r
\r
  Notes:\r
  This driver assumes the following ReportStatusCode strategy:\r
  PEI       -> uses PeiReportStatusCode\r
  DXE IPL   -> uses PeiReportStatusCode\r
  early DXE -> uses PeiReportStatusCode via HOB\r
  DXE       -> This driver\r
  RT        -> This driver\r
