brcmfmac: Change USB probe routine to support Composite USB
Some of the USB devices also have Bluetooth inside. These devices can with specific firmware result in a composite USB device. This change will update the driver such that it will also accept the correct interface of composite devices. It is backward compatible with old non-composite USB fw.
