Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.13-20180504' into staging

ppc patch queue 2018-05-04

Second patch of patches for qemu-2.13 (or whatever the version ends up
being called).  Highlights are:
  * Preliminary patches for POWER9 hash MMU support for powernv
  * A number of cleanups fo pseries startup and LPCR handling
  * Remove support for explicitly allocated RMAs (which require kernel
    support that's been gone for 3+ years)
  * Some mac_newworld cleanups
  * A few bugfixes

* remotes/dgibson/tags/ppc-for-2.13-20180504:
  spapr: don't advertise radix GTSE if max-compat-cpu < power9
  spapr: don't migrate "spapr_option_vector_ov5_cas" to pre 2.8 machines
  target/ppc: always set PPC_MEM_TLBIE in pre 2.8 migration hack
  mac_newworld: move wiring of macio IRQs to macio_newworld_realize()
  mac_newworld: remove pics IRQ array and wire up macio to OpenPIC directly
  uninorth: create new uninorth device
  spapr: Clean up handling of LPCR power-saving exit bits
  spapr: Move PAPR mode cpu setup fully to spapr code
  target/ppc: Delay initialization of LPCR_UPRT for secondary cpus
  spapr: Clean up LPCR updates from hypercalls
  spapr: Make a helper to set up cpu entry point state
  spapr: Remove unhelpful helpers from rtas_start_cpu()
  spapr: Clean up rtas_start_cpu() & rtas_stop_self()
  target/ppc: Add ppc_store_lpcr() helper
  spapr: Remove support for explicitly allocated RMAs
  target/ppc: add basic support for PTCR on POWER9
  target/ppc: return a nil HPT base address on sPAPR machines
