AMD Olivehill: Add ACPI Sx call for southbridge into _PTS

The Sx for southbridge calls are in AlibSsdtKB. The original ASL code
    has been scrubbed.

Without the calls, Olive Hill can not wake up if it boots Windows.

TODO: 1. Populate to other board.
          2. If the board is wake up by USB keyboard, Sleeping again will wake
             up immediately without pressing any button.
