powerpc/32: Fix objtool unannotated intra-function call warnings
Fix several annotations in assembly files on PPC32.
[Sathvika Vasireddy: Changed subject line and removed Kconfig change to
enable objtool, as it is a part of "objtool/powerpc: Enable objtool to
be built on ppc" patch in this series.]
