ASoC: Updates for v5.17

Not much going on framework release this time, but a big update for
drivers especially the Intel and SOF ones.

 - Refinements and cleanups around the delay() APIs.
 - Wider use of dev_err_probe().
 - Continuing cleanups and improvements to the SOF code.
 - Support for pin switches in simple-card derived cards.
 - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
   systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
   S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
   TLV320ADC3xxx.
