arch/powerpc/kernel/ contains 8 files dedicated to kexec.

Move them into a dedicated subdirectory.

v2: moved crash.c as well as it's part of kexec suite.
v3: renamed files to remove 'kexec' keyword from names.
v4: removed a ifdef in kexec/Makefile

I'm inclined to move the directory out of kernel, ie. up a level with mm
and so on.

And I also don't think the "machine" naming is useful anymore. It comes
from the naming of the arch functions, eg. machine_kexec(), which was
named to be analogous to machine_restart().

So how about:

arch/powerpc/{kernel/machine_kexec.c => kexec/core.c}
arch/powerpc/{kernel/machine_kexec_32.c => kexec/core_32.c}
arch/powerpc/{kernel/machine_kexec_64.c => kexec/core_64.c}
arch/powerpc/{kernel => kexec}/crash.c
arch/powerpc/{kernel/kexec_elf_64.c => kexec/elf_64.c}
arch/powerpc/{kernel/machine_kexec_file_64.c => kexec/file_load.c}
arch/powerpc/{kernel/ima_kexec.c => kexec/ima.c}
arch/powerpc/{kernel/kexec_relocate_32.S => kexec/relocate_32.S}

And we end up with:

$ find arch/powerpc/kexec
arch/powerpc/kexec/
arch/powerpc/kexec/file_load.c
arch/powerpc/kexec/relocate_32.S
arch/powerpc/kexec/core_64.c
arch/powerpc/kexec/ima.c
arch/powerpc/kexec/core.c
arch/powerpc/kexec/core_32.c
arch/powerpc/kexec/Makefile
arch/powerpc/kexec/crash.c
arch/powerpc/kexec/elf_64.c

That looks good
