soundwire updates for v5.6-rc1

This round we have bunch of updates to interfaces for ASoC (audio)
subsystem by Intel and a new Qualcomm controller driver

Details
 - Updates for sdw_slave interfaces for ASoC
 - Updates to cadence library and intel driver
 - New Soundwire controller for Qualcomm masters
 - Rework of device number assignment
