[PATCH master 3/4] console: define barebox_set_loglevel

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

Selftests may want to change barebox_loglevel temporarily to avoid expected
warning or error messages cluttering the log. barebox_loglevel is only
defined for !CONFIG_CONSOLE_NONE though, so add a stub for the
console-less case.
