printk: Set console_set_on_cmdline=1 when __add_preferred_console() is called with user_specified == true
In case of using console="" or console=null set console_set_on_cmdline=1 to disable "stdout-path" node from DT. We basically need to set it every time when __add_preferred_console() is called with parameter 'user_specified' set. Therefore we can move setting it into a helper function that is called from __add_preferred_console().
