Add support for automatically discover available platforms. The Python-side uses functionality similar to what we use when auto-detecting available CPU models. The machine IDs have been updated to match the platform configurations. If there isn't a matching machine ID, the configuration scripts default to -1 which Linux uses for device tree only platforms.
