of: fix up /chosen node even when there are no bootargs
Currently the /chosen fixups of "reset-source",
"reset-source-instance", "reset-source-device" and "bootsource" do not
happen if no bootargs are available.
Fix that by moving the actual bootargs fixup to a dedicated function
of_write_bootargs() and only return there early on empty bootargs, but
still perform the /chosen fixups mentioned above.
