driver-core: Add device node pointer to struct device

Currently, platforms using CONFIG_OF add a 'struct device_node *of_node'
to dev->archdata.  However, with CONFIG_OF becoming generic for all
architectures, it makes sense for commonality to move it out of archdata
and into struct device proper.

This patch adds a struct device_node *of_node member to struct device
and updates all locations which currently write the device_node pointer
into archdata to also update dev->of_node.  Subsequent patches will
modify callers to use the archdata location and ultimately remove
the archdata member entirely.
