amd/pi/hudson: Move audio to northbridge

Carrizo (00660F01), Merlin Falcon (00660F01), and Stoney Ridge (00670F00)
locate the HD audio controller on the northbridge root complex at 9.2
instead of the FCH.  This duplicates the existing ASL into the northbridge
directories and reports the correct address.
