Mikhail Naganov b2f1c0f857 audio hal: Allow using multiple devices with IStream.get/setDevice ...

To retain compatibility with existing usages of the "routing"
parameter, IStream.setDevice method must accept multiple devices
(as DeviceAddress). This happens when the patch being created
has multiple sinks.

As a consequence, IStream.getDevices needs to return a vector of
DeviceAddress structs.
