While cleaning up the last few -Wimplicit-fallthrough warnings in tree
for Clang, I noticed
commit 6a9dc5fd6170d ("lib: Revert use of fallthrough pseudo-keyword in lib/")
which seemed to undo a bunch of fixes in lib/ due to breakage in
arch/powerpc/boot/ not including compiler_types.h.  We don't need
compiler_types.h for the definition of `fallthrough`, simply
compiler_attributes.h.  Include that, revert the revert to lib/, and fix
the last remaining cases I observed for powernv_defconfig.

Nick Desaulniers (3):
  powerpc: boot: include compiler_attributes.h
  Revert "lib: Revert use of fallthrough pseudo-keyword in lib/"
  powerpc: fix -Wimplicit-fallthrough
