From: Ahmad Fatoum <a.fatoum@pengutronix.de>

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.

[bst: dropped new line deletions and modified string comparison, moved of_write_bootargs() call to original position, add commit message]
