ASoC: Fixes for v6.17

The main fixes here are for some of the cleanups done in the core in
this release, we had broken component lookup in the case with a single
bus and DMA controller.  Otherwise it's driver specific changes, the
shortlogs for the Intel WCL and rsnd drivers look like minor cleanups
but are actually bugfixes (adding an op needed for correct functionality
and reverting an inappropriate helper usage).
