[PATCH RFC 09/10] qdev: Refactor and rename of qdev_class_add_property()

[Peter Xu <peterx@redhat.com>]

Firstly, qdev_class_add_property() function almost has nothing to do with
DeviceClass, it's a bridge between Property and object properties.

Change the 1st parameter of it, so that it can be used without DeviceClass
context at all. When at it, remove the "name" field because it's always
prop->name.

Export it for non-qdev use cases.
