dt-bindings: soc: qcom,wcnss: fix bluetooth address example

The 'local-bd-address' property is used to pass a unique Bluetooth
device address from the boot firmware to the kernel and should otherwise
be left unset.

Update the example to reduce the risk that a non-zero address will be
used by default in some devicetree.
