qcacmn: WMI service ready convergence changes

Converge on common WMI event handling for (ext)service ready
such that common PSOC object can be populated after common parsing.
Legacy (ext)service ready handlers continue to co-exist to support
legacy modules. Legacy service ready handlers can be removed once
legacy modules are also componentized and start using new object
model of PSOC, PDEV, VDEV and PEER.

To support multiple SoCs register for various psoc objects via legacy
callback registration routine during psoc probe and populate common
psoc object once WMI (ext)service ready event is parsed.
