ASoC: Updates for v5.19

This is quite a big update, partly due to the addition of some larger
drivers (more of which is to follow since at least the AVS driver is
still a work in progress) and partly due to Charles' work sorting out
our handling of endianness.  As has been the case recently it's much
more about drivers than the core.

 - Overhaul of endianness specification for data formats, avoiding
   needless restrictions due to CODECs.
 - Initial stages of Intel AVS driver merge.
 - Introduction of v4 IPC mechanism for SOF.
 - TDM mode support for AK4613.
 - Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
   MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
   nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780
