driver core: platform: provide platform_device_set_fwnode()
Provide a helper function encapsulating the logic of assigning firmware
nodes to platform devices created with platform_device_alloc(). Make the
kerneldoc state that this is the proper interface for assigning firmware
nodes to dynamically allocated platform devices. This will allow us to
switch to counting the references of the device's firmware nodes in the
future, not only the OF nodes.
