  SA DXE Policy

 The SA_POLICY_PROTOCOL producer drvier is recommended to
 set all the SA_POLICY_PROTOCOL size buffer zero before init any member parameter,
 this clear step can make sure no random value for those unknow new version parameters.

 Make sure to update the Revision if any change to the protocol, including the existing
 internal structure definations.\n
  Note: Here revision will be bumped up when adding/removing any config block under this structure.\n
  <b>Revision 1</b>:
  - Initial version.
