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