Subject: [PATCH v2 1/3] soundwire: extend parameters of new_peripheral_assigned() callback

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

The parameters are only the bus and the device number, manager ops may
need additional details on the type of peripheral connected, such as
whether it is wake-capable or not.
