SystemTable should be MmSystemTable.

These feedback may be also applied to the implementation in next patch.

With them handled, Acked-by: Star Zeng <star.zeng@intel.com> to this and 
next patches.

Ard:
  I have no other comment for the changes in MdePkg. You can add my R-B for MdePkg. Besides, I have updated our internal platform too consume new MmServicesTableLib. 

Thanks

Thank you Liming. I will go through all Star's comments, and fix up
the patches before pushing.

What about the Quark and Vlv2 changes? (adding MmServicesTableLib)
