amd/stoneyridge: Load AOAC and USB gnvs values
Indicate the devices that are enabled. This is somewhat rudimentary, but
could be improved in a later patch (e.g. get settings from devicetree).
Calculate values that may be used for reinitializing the xHCI firmware.
Add the EHCI BAR's current base address to gnvs.
