AMD Kabini: Add ACPI sleep/wakeup calls for southbridge 

The AML code of PTS and WAK for southbridge are in
UINT8  AlibSsdtKB[], Proc/GNB/Modules/GnbInitKB/AlibSsdtKB.h.
It was integrated into SSDT even it was called by nobody.
The source ASL was provided by AGESA for reference, but it
has been scrubbed when it was ported to Coreboot.

Without the calls, Olive Hill can not wake up if it boots Windows.
Both amd/olivehill and asrock/imb-a180 have been validated.
