soundwire updates for v5.8-rc1

This contains sdw_master_device patches and other updates done by Intel
folks.

Details:
  - sdw_master_device to represent the master instances.
  - sysfs properties for sdw_master_device and sdw_slave.
  - Documentation update for TDM modes.
  - some code cleanup patches and odd updates.
