Kconfig does not allow you to have the same symbol as both a regular
'bool' and also 'bool within choice', so those three have to replace the
choice with a user-visible 'config CPU_BIG_ENDIAN' option like the
other ones have.
I also notice that for arch/s390/Kconfig you now have both the
'select CPU_BIG_ENDIAN' and the 'config CPU_BIG_ENDIAN
def_bool y', I'd remove the second one in the same patch.
