Subject: [PATCH 02/11] soundwire: intel: simplify flow and use devm_ for DAI registration

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

We already use devm_ for memory allocation but not for component/DAI
registration. The resource management can be based on devm_ in all
cases.
