powerpc: Kconfig: remove BE-only platforms from LE kernel build
Currently, little endian is only supported on powernv and pseries, however, Kconfigs still allow us to include other platforms in a LE kernel, this may result in space wasting or even build error if some BE-only platforms always assume they are built for a BE kernel. So just modify the Kconfigs of BE-only platforms to remove them from being built for a LE kernel. For 32bit only platforms, nothing needs to be done, because CPU_LITTLE_ENDIAN depends on PPC64. For 64bit supported platforms, add CPU_BIG_ENDIAN to dependencies explicitly, so that these platforms will be disabled for LE [Suggested-by: Cédric Le Goater <clg@fr.ibm.com>].
