fw_config: Add helper function `fw_config_probe_dev`
This change adds a helper function `fw_config_probe_dev()` that allows
the caller to check if any of the probe conditions are true for any
given device. If device has no probe conditions or a matching probe
condition, then it returns true and provides the matching probe
condition back to caller (if provided with a valid pointer). Else, it
returns false. When fw_config support is disabled, this function
always returns true.
