fw_config: Use UNDEFINED_FW_CONFIG to mean unprovisioned
A mainboard might want to configure some things differently when a device is in an unprovisioned state. In the case when fw_config comes from the Chromium EC, an unprovisioned device will not have a FW_CONFIG tag in its CBI. This patch will set the fw_config value to UNDEFINED_FW_CONFIG in the case of an error retrieving the value, as well as adding a function, `fw_config_is_provisioned()` to indicate the provisioning status. BUG=none TEST=remove fw_config from chromium EC CBI, add code to mainboard to print return value of fw_config_is_provisioned() (`0`), add fw_config back to CBI, run same test and see `1`.
