NVRAM, ChipCommon, etc). This extends the existing handling of NVRAM core discovery to support locating additional devices that may be attached either directly as real cores, or indirectly via ChipCommon (e.g. bhnd_pmu). When attached as a SoC root bus (as opposed to a bridged WiFi device), the platform devices may not be attached until later bus passes, necessitating delayed discovery/initialization.
