[PATCH-for-5.1 v3 11/24] hw/arm/msf2-soc: Store MemoryRegion in MSF2State

[Philippe Mathieu-Daudé]

Coccinelle reported:

  $ spatch ... --timeout 60 --sp-file \
    scripts/coccinelle/simplify-init-realize-error_propagate.cocci
  HANDLING: ./hw/arm/msf2-soc.c
  >>> possible moves from m2sxxx_soc_initfn() to m2sxxx_soc_realize() in 
./hw/arm/msf2-soc.c:86

While reviewing we notice storing the MemoryRegion in the device
state, we'll be able to later automatically simplify the error
propagation calls.
