[PATCH v3 53/53] sev: Use class properties

[Eduardo Habkost]

Instance properties make introspection hard and are not shown by
"-object ...,help".  Convert them to class properties.

This is a new patch added in v3 of this series.

There was another version of this patch inside series:
  Subject: [PATCH 00/12] qom: Make all -object types use only class properties
  Message-Id: <20201009160122.1662082-1-ehabkost@redhat.com>
  
https://lore.kernel.org/qemu-devel/20201009160122.1662082-1-ehabkost@redhat.com

Changes from v1 of the patch:
* Use new object_class_property_add_field() API
  to replace object_property_add_uint32_ptr().
  (v1 used object_class_property_add_uint32_ptr(), which won't
  exist anymore)
