soundwire: mipi-disco: add support for DP0/DPn 'lane-list' property
The SoundWire specification did not clearly require that ports could use all Lanes. Some SoundWire/SDCA peripheral adopters added restrictions on which lanes can be used by what port, and the DisCo for SoundWire 2.1 specification added a 'lane-list' property to model this hardware limitation. When not specified, the ports can use all Lanes. Otherwise, the 'lane-list' indicates which Lanes can be used, sorted by order of preference (most-preferred-first). This patch only reads the properties, the use of this property will come at a later time with multi-lane support.
