Subject: [RFC PATCH v3 11/12] powerpc: Remove unreachable() from WARN_ON()

objtool is throwing *unannotated intra-function call*
warnings with a few instructions that are marked
unreachable. Remove unreachable() from WARN_ON()
to fix these warnings, as the codegen remains same
with and without unreachable() in WARN_ON().
