driver core: add a helper to setup both the of_node and fwnode of a device

Browse source 
[ Upstream commit 43e76d463c09a0272b84775bcc727c1eb8b384b2 ]

There are many places where both the fwnode_handle and the of_node of a
device need to be populated. Add a function which does both so that we
have consistency.
