Since f94277af03ea ("of/platform: Initialise dev->fwnode appropriately"),
of_platform_device_create() already initialises dev->fwnode to that of
the appropriate device_node, so within the driver we shouldn't need to
care whether we probed via DT or ACPI.

Not tested, just an opportunity I happened to spot whilst looking
at something else.
