util/sconfig: Probe device when fw_config is unprovisioned

When fw_config is unprovisioned (eg. in the factory), devices that do
not have any probe list are enabled by default and those that have probe
list are disabled. On mainboards that support multiple types of boot
critical devices (eg. storage) through probing fw_config, all of
them are disabled when fw_config is unprovisioned. Hence the devices do
not boot to OS. Add sconfig fw_config rule `probe unprovisioned` to
enable such devices when fw_config is unprovisioned.

BUG=None
TEST=Build Brox firmware and boot to OS when fw_config is unprovisioned.
