This series of patches disables the TPM 2 platform hierarchy.
We just added the same functionality to the OvmfPkg. However, on x86, we
could use the notification mechanism around gEfiDxeSmmReadyToLockProtocolGuid
to indirectly invoke ConfigureTpmPlatformHierarchy(). Since ARM does not
have an SMM mode this series now use direct invocation of this function
at the same place in PlatformBootManagerBeforeConsole() as it is done
on x86.

Regards,
   Stefan

  - Move Null implementation to SecurityPkg
