Merge remote-tracking branch 'afaerber/tags/qom-devices-for-anthony' into staging

QOM device refactorings

* Replace all uses of FROM_SYSBUS() macro with QOM cast macros
  i) "QOM cast cleanup for X"
     Indicates a mechanical 1:1 between TYPE_* and *State.
  ii) "QOM'ify X and Y"
      Indicates abstract types may have been inserted or similar changes
      to type hierarchy.
  ii) Renames
      Coding Style fixes such as CamelCase have been applied in some cases.
* Fix for sparc floppy - cf. ii) above
* Change PCI type hierarchy to provide PCI_BRIDGE() casts
* In doing so, prepare for adopting QOM realize
