amd/stoneyridge: Create gnvs entries for AOAC devices
A later patch will leverage AMD's ASL support for handling AOAC
devices. This will gather coreboot's device enables from a bitwise field,
where each bit corresponds to the register offset used to control
each devices.
Create an identical structure, and add it to the nvs ASL and global_nvs_t
structure.
