[PATCH for-7.1 2/4] hw/ppc: use qdev to register physical DRC vmstates

[Daniel Henrique Barboza <danielhb413@gmail.com>]

Similar to logical DRCs, let's convert physical DRCs to register their
vmstates using dc->vmsd.

The same constraints with instance_id being set to spapr_drc_index()
also applies in this case. However, since realize_physical() calls
drc_realize(), qdev_set_legacy_instance_id() is already being set.
