ASoC: Updates for v5.2

This is a pretty huge set of changes, it's been a pretty active release
all round but the big thing with this release is the Sound Open Firmware
changes from Intel, providing another DSP framework for use with the
DSPs in their SoCs.  This one works with the firmware of the same name
which is free software (unlike the previous DSP firmwares and framework)
and there has been some interest in adoption by other systems already so
hopefully we will see adoption by other vendors in the future.

Other highlights include:

 - Support for MCLK/sample rate ratio setting in the generic cards.
 - Support for pin switches in the generic cards.
 - A big set of improvements to the TLV320AIC32x4 drivers from Annaliese
   McDermond.
 - New drivers for Freescale audio mixers, several Intel machines,
   several Mediatek machines, Meson G12A, Sound Open Firmware and
   Spreadtrum compressed audio and DMA devices.
