Michael Ellerman acd4dfeb49 powerpc/kexec: Don't use .machine ppc64 in trampoline_64.S
As best as I can tell the ".machine" directive in trampoline_64.S is no
longer, or never was, necessary.

It was added in commit 0d97631392 ("powerpc: Add purgatory for
kexec_file_load() implementation."), which created the file based on
the kexec-tools purgatory. It may be/have-been necessary in the
kexec-tools version, but we have a completely different build system,
and we already pass the desired CPU flags, eg:

  gcc ... -m64 -Wl,-a64 -mabi=elfv2 -Wa,-maltivec -Wa,-mpower4 -Wa,-many
  ... arch/powerpc/purgatory/trampoline_64.S

So drop the ".machine" directive and rely on the assembler flags.
