Subject: [PATCH 1/2] Revert "kexec: purgatory: add clean-up for purgatory directory"

This reverts commit b0108f9e93d0d39050eaa11358852f349bdccb71.

Commit b0108f9e93d0 ("kexec: purgatory: add clean-up for purgatory
directory") stated that the kexec-purgatory.c and purgatory.ro files
were not removed after make mrproper.

In fact, they are.  You can confirm it after reverting it.

  $ make mrproper
  $ touch arch/x86/purgatory/kexec-purgatory.c
  $ touch arch/x86/purgatory/purgatory.ro
  $ make mrproper
    CLEAN   arch/x86/purgatory
  $ ls arch/x86/purgatory/
  entry64.S  Makefile  purgatory.c  setup-x86_64.S  stack.S  string.c

This is obvious from the build system point of view.

arch/x86/Makefile adds 'arch/x86' to core-y.
Hence 'make clean' descends like this:

  arch/x86/Kbuild
    -> arch/x86/purgatory/Makefile
