mb/google/brox: Enable storage devices on unprovisioned fw_config

Storage devices are very critical to boot to OS. When probe list is
defined for storage devices, all of them get disabled when fw_config is
unprovisioned - a typical situation in the factory. Fix this by
configuring the storage devices in device/override tree to probe and
enable them when fw_config is unprovisioned.

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