The existing SoundWire support misses a clear Controller/Manager hiearchical definition to deal with all variants across SOC vendors. a) Intel platforms have one controller with 4 or more Managers. b) AMD platforms have two controllers with one Manager each, but due to BIOS issues use two different link_id values within the scope of a single controller. c) QCOM platforms have one or more controller with one Manager each. This patch adds a 'controller_id' which can be set by higher levels. If assigned to -1, the controller_id will be set to the system-unique IDA-assigned bus->id. The main change is that the bus->id is no longer used for any device name, which makes the definition completely predictable and not dependent on any enumeration order. The bus->id is only used to insert the Managers in the stream rt context.
