[PATCH 01/16] powerpc: Replace unreachable() with it's builtin variant in WARN_ON()

objtool is throwing *unannotated intra-function call*
warnings with a few instructions that are marked
unreachable. Replace unreachable() with __builtin_unreachable()
to fix these warnings, as the codegen remains same
with unreachable() and __builtin_unreachable().
