of/platform: Initialise dev->fwnode appropriately

Browse Source 
Whilst we're some of the way towards a universal firmware property
interface, drivers which deal with both OF and ACPI probing end up
having to do things like this:

    dev->of_node ? &dev->of_node->fwnode : dev->fwnode

This seems unnecessary, when the OF code could instead simply fill in
the device's fwnode when binding the of_node, and let the drivers use
dev->fwnode either way. Let's give it a go and see what falls out.
