In fact it 's not command line retrieved from efi or fdt, but the built-in
command line to be concerned. CONFIG_CMDLINE was never been touched during
boot on loongarch, unless CONFIG_CMDLINE_FORCE is set because there is code
handling this. There should be code handling CONFIG_CMDLINE_FORCE and
CONFIG_CMDLINE_EXTEND as well but is absent by now.
