[PATCH 3/3] fixup! commands: implement rksecure command

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

commands: rksecure: use printf for command errors

pr_err is logged, may be shared with Linux via pstore and outputs to stderr,
which may point at a different console or be hidden by log level setting.

printf on the other hand is not logged, uses stdout and is thus the
correct function to use to output, regular or error, in commands.
