ASoC: Updates for v6.13

This release was mainly about new drivers, there's a very large batch of
new drivers and devices including quite a few from newer vendors which
is great to see.  Other than the new drivers and the usual routine fixes
and enhancements the bulk of the work has been Morimoto-san's continuing
work on simplifiying APIs, plus a few other bits:

 - More API simplifications from Morimoto-san.
 - Renaming of the sh directory to Renesas to reflect the focus on other
   architectures.
 - Factoring out of some of the common code for Realtek devices.
 - Support for Allwinner H616, AMD ACP 6.3 systems, AWInic AW88081,
   Cirrus Logic CS32L84, Everest ES8328, Iron Devices SMA1307, Longsoon
   I2S, NeoFidelity NTP8918 and NTP8835, Philips UDA1342, Qualcomm
   SM8750, RealTek RT721, and ST Microelectronics STM32MP25.
