Lots of changes in this cycle, but mostly for cleanups and
refactoring. Significant amount of changes are about DT schema
conversions for ASoC at this time while we see other usual
suspects, too. Some highlights below:
Core:
- Re-introduction of PCM sync ID support API
- MIDI2 time-base extension in ALSA sequencer API
ASoC:
- Syncing of features between simple-audio-card and the two
audio-graph cards
- Support for specifying the order of operations for components
within cards to allow quirking for unusual systems
- Lots of DT schema conversions
- Continued SOF/Intel updates for topology, SoundWire, IPC3/4
- New support for Asahi Kasei AK4619, Cirrus Logic CS530x, Everest
Semiconductors ES8311, NXP i.MX95 and LPC32xx, Qualcomm LPASS
v2.5 and WCD937x, Realtek RT1318 and RT1320 and Texas
Instruments PCM5242
HD-audio:
- More quirks, Intel PantherLake support, senarytech codec support
- Refactoring of Cirrus codec component-binding
Others:
- ALSA control kselftest improvements, and fixes for input value
checks in various drivers

The struct instances supplied by the drivers are never modified.
Handle them as const in the regmap core allowing the drivers to put them
into .rodata.
Also add a new entry to const_structs.checkpatch to make sure future
instances of this struct already enter the tree as const.
