Subject: [PATCH 03/11] soundwire: intel: move DAI registration and debugfs init earlier

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

These two steps can and should be done before starting up the clock
and the bus operation. This is a first step before re-grouping
functionality in well-defined callbacks.
