Krzysztof Kozlowski 8a8a9ac8a4 soundwire: fix initializing sysfs for same devices on different buses
If same devices with same device IDs are present on different soundwire
buses, the probe fails due to conflicting device names and sysfs
entries:

  sysfs: cannot create duplicate filename '/bus/soundwire/devices/sdw:0:0217:0204:00:0'

The link ID is 0 for both devices, so they should be differentiated by
the controller ID. Add the controller ID so, the device names and sysfs entries look
like:

  sdw:1:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6ab0000.soundwire-controller/sdw-master-1-0/sdw:1:0:0217:0204:00:0
  sdw:3:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6b10000.soundwire-controller/sdw-master-3-0/sdw:3:0:0217:0204:00:0

[PLB changes: use bus->controller_id instead of bus->id]
