ASoC: Updates for v7.0

This release is almost all abut driers, there's very little core work
here, although some of that driver work is in more generic areas like
SDCA and SOF:

 - Generic SDCA support for reporting jack events.
 - Continuing platform support, cleanup and feature improements for the
   AMD, Intel, Qualcomm and SOF code.
 - Platform description improvements for the Cirrus drivers.
 - Support for NXP i.MX952, Realtek RT1320 and RT5575, and Sophogo
   CV1800B.

We also pulled in one small SPI API update and some more substantial
regmap work (cache description improvements) for use in drivers.
