ASoC: Updates for v5.16

This is an unusually large set of updates, mostly a large crop of
unusually big drivers coupled with extensive overhauls of existing code.
There's a SH change here for the DAI format terminology, the change is
straightforward and the SH maintainers don't seem very active.

 - A new version of the audio graph card which supports a wider range of
   systems.
 - Move of the Cirrus DSP framework into drivers/firmware to allow for
   future use by non-audio DSPs.
 - Several conversions to YAML DT bindings.
 - Continuing cleanups to the SOF and Intel code.
 - A very big overhaul of the cs42l42 driver, correcting many problems.
 - Support for AMD Vangogh and Yelow Cap, Cirrus CS35L41, Maxim
   MAX98520 and MAX98360A, Mediatek MT8195, Nuvoton NAU8821, nVidia
   Tegra210, NXP i.MX8ULP, Qualcomm AudioReach, Realtek ALC5682I-VS,
   RT5682S, and RT9120 and Rockchip RV1126 and RK3568
