Commit 3d45a3d0d2e6 ("powerpc: Define config option for processors with broadcast
TLBIE")
added a config option PPC_RADIX_BROADCAST_TLBIE to support processors with
broadcast TLBIE. Since this option is relevant only for RADIX_MMU, add
a check as a dependency to enable PPC_RADIX_BROADCAST_TLBIE in both
powernv and pseries configs. This fixes the unmet config dependency
warning reported
