Begin to consolidate of_device.c
This moves all the common parts for the Sparc, Sparc64 and PowerPC
of_device.c files into drivers/of/device.c.
Apart from the simple move, Sparc gains of_match_node() and a call to
of_node_put in of_release_dev(). PowerPC gains better recovery if
device_create_file() fails in of_device_register().
