This allows a board to be booted without the need of having a console parameter in the kernel command line. Currently the Spring DTS has bootargs in the /chosen node and this is kept since users that don't have a serial console on this board might be using it to have the boot log shown in the display. This will have more precedence than the stdout-path but it's fine since is only used when CONFIG_ARM_ATAG_DTB_COMPAT_CMDLINE_EXTEND is enabled.
