MIPS: Loongson{2ef,64}: Wrap -mno-branch-likely with cc-option
This flag is not supported by clang, which results in a warning:
clang-14: warning: argument unused during compilation: '-mno-branch-likely' [-Wunused-command-line-argument]
This breaks cc-option, which adds -Werror to make this warning fatal and
catch flags that are not supported.
Wrap this flag in cc-option so that it does not cause cc-option to fail,
which can cause randconfigs to be really noisy, due to warnings not
getting disabled that should be.
Additionally, move the cc-option check to Kconfig so that the check is
done at configuration time, rather than build time, as builds with no
configuration change will be quicker because the cc-option call will not
need to happen in those instances.
