Subject: [RFC PATCH v1 5/9] driver core: Set fw_devlink.strict=1 by default

Now that deferred_probe_timeout is non-zero by default, fw_devlink will
never permanently block the probing of devices. It'll try its best to
probe the devices in the right order and then finally let devices probe
even if their suppliers don't have any drivers.
