sound updates for 7.2-rc1

Unsurprisingly, we've had a fairly busy development cycle with
various fixes and enhancements.  While the majority of changes consist
of device-specific fixes, a significant number of cleanups, hardening,
and modernizations have been applied to the core frameworks as well.

Below are some highlights:

* ALSA Core:
- Hardening, race condition, and UAF/leak fixes in the ALSA timer and
  sequencer cores
- Widespread adoption of flexible array members across core structures
- Integration of new simple refcount helper functions to simplify code

* ASoC Core:
- Introduction of a unified SoundWire enumeration helper to clean up
  redundant device initialization across codecs
- Enhancements to SDCA support, including handling devices with
  multiple functions of the same type and proper jack reporting masks
- Continued refactoring of ASoC component debugfs and DAPM structures
- Simplification and improvements to the format auto-selection
  mechanism
- Added shared BCLK rate constraints for cross-DAI coordination

* ASoC Platforms & Codecs:
- Initial bring-up and power management support for AMD ACP 7.x
- Support for Everest Semi ES9356 (SDCA), Mediatek MT2701 (on-chip
  HDMI) and MT8196 SoCs, Renesas RZ/G3E, SpacemiT K3, and TI
  TAC5xx2/TAS67524
- Added a new generic driver for GPIO-driven amplifiers
- Continued mass conversion of locking code to guard() helpers across
  numerous platform drivers (MediaTek, Rockchip, STM32, Samsung, etc.)
- Cleanup of legacy non-DT platform data and rollbacks for obsolete SH
  Ecovec24/7724se boards

* HD- and USB-Audio:
- Device-specific hardware quirks and fixes for various Realtek
  HD-Audio devices (Lenovo, HP, ASUS, Acer, Clevo)
- Refinements to Qualcomm USB-audio offloading support
- Front-panel controls and autogain status support for Scarlett Gen 4
- Quirks for XIBERIA (K03S), Sennheiser (MOMENTUM 3), Edifier (MF200),
  Novation (Mininova), and Behringer (Flow 8) USB-audio devices
- Improved robustness by rolling back or propagating write errors to the
  mixer control caches (Babyface Pro, US-16x08, Scarlett)

* Others:
- Support for the HT-Omega eClaro PCI sound card in the Oxygen driver
- Robustness improvements and fixes for Virtio-audio, Xen-front, and
  legacy OSS dmasound drivers

ASoC: Updates for v7.2

There's been quite a lot of framework improvements this time around,
though mainly cleanups and robustness rather than user visible features.
The same pattern is seen with a lot of the driver work that's going on,
there are new features but a huge proportion of this is bug fixing and
cleanup work.  We also have a good selectio of new device support.

 - Improvements to SDCA jack handling from Charles Keepax.
 - Use of device links to make suspend handling more robust from Richard
   Fitzgerald.
 - Use of a new helper to factor out a common pattern in SoundWire
   enmeration from Charles Keepax.
 - Slimming down of the component from Kuninori Morimoto.
 - Simplification of format auto selection from Kuninori Morimoto.
 - Lots of conversions to guard() from Bui Duc Phuc.
 - Addition of a simple-amplifier driver supporting more featureful GPIO
   controller amplifiers than the previous basic driver from Herve
   Codina.
 - Support for AMD ACP 7.x, Cirrus Logic CS42448/CS42888, Everest Semi
   ES9356, Mediatek MT2701 and MT8196, Renesas RZ/G3E, Spacemit K3,
   Texas Instruments TAC5xx2 and TAS67524.
