docs/zephyr: Update docs to reflect device name changes.
Zephyr v3.2.0 deprecated the devicetree label property as a base
property, which had been used as the device name string for
device_get_binding(). The device name string is now the devicetree node
name appended with its unit-address. Update Zephyr port documentation
to reflect this change.
