amd/stoneyridge: Add ASL for D-states on AOAC devices

Browse source 
Duplicate ASL from AMD's FchCarrizo.asl (available in NDA PI package)
that can put AOAC devices into D0 or D3cold.  The argument numbers
coincide with the AOAC register offsets for the various devices.

SATA, USB, and SD require additional device configuration.  Add a
placeholder and mark as todo.
