      ACPI PM: Add possibility to change suspend sequence
      
      There are some systems out there that don't work correctly with
      our current suspend/hibernation code ordering.  Provide a workaround
      for these systems allowing them to pass 'acpi_sleep=old_ordering' in
      the kernel command line so that it will use the pre-ACPI 2.0 ("old")
      suspend code ordering.
      
      Unfortunately, this requires us to add a platform hook to the
      resuming of devices for recovering the platform in case one of the
      device drivers' .suspend() routines returns error code.  Namely,
      ACPI 1.0 specifies that _PTS should be called before suspending
      devices, but _WAK still should be called before resuming them in
      order to undo the changes made by _PTS.  However, if there is an
      error during suspending devices, they are automatically resumed
      without returning control to the PM core, so the _WAK has to be
      called from within device_resume() in that cases.
      
      The patch also reorders and refactors the ACPI suspend/hibernation
      code to avoid duplication as far as reasonably possible.
