This new version contains fixes proposed during the review of v3.
Patches were rebased on top of David's ppc-for-6.0.

changes from v3:
- former patch 1: already pushed to ppc-for-6.0
- former patch 2: dropped
- all patches: commit message trimmed to < 76 chars per line
- all patches: added R-bs from previous review
- patch 3:
    * removed the migratable state of the unplug timer
    * added a 'spapr_drc_start_unplug_timeout_timer()' helper to start the timer
    * added a .post_load implementation to vmstate_spapr_drc, pointed to
      a new spapr_drc_post_load() function
    * spapr_drc_post_load() starts the DRC unplug timer from the beginning using

- patch 4:
    * use spapr_drc_start_unplug_timeout_timer() to start the timer in 
    (To David: I kept your Reviewed-by in this patch despite this change - feel 
     to review it again)

- patch 5:
    * removed the 'DIMM' wording when referring to kernel internals
    * move the g_assert() to spapr_clear_pending_dimm_unplug_state()
    * do not g_assert(dev), but g_assert(ds) if dev != NULL inside
