[PATCH for-7.1 0/4] use dc->vmsd with spapr devices vmstate

[Daniel Henrique Barboza]

Hi,

This short series converts some spapr devices to use the dc->vmsd
interface to register the vmstate. For most of them it was needed
to use qdev_set_legacy_instance_id() to keep compatibility with the
instance_id being used for awhile.

Although no functional changes were made the resulting code is a bit
shorter and maintainable. After these patches there are only 3 places
where vmstate_register() APIs are being used.

No behavior changes were detected when testing migration scenarios with
hotplug/unplug of devices.

Daniel Henrique Barboza (4):
  hw/ppc: use qdev to register logical DRC vmstates
  hw/ppc: use qdev to register physical DRC vmstates
  hw/ppc: use qdev to register spapr_iommu tcet vmstate
  hw/ppc: use qdev to register spapr_nvdimm vmsd
