MAX98390 is a smart amplifier and exposes one DAI, so '#sound-dai-cells'
property is needed for describing the DAI links.

Reference the dai-common.yaml schema to allow '#sound-dai-cells' to be
used.

This fixes dtbs_check error:
  '#sound-dai-cells' does not match any of the regexes: 'pinctrl-[0-9]+'

This patch is based on a previous [v1] series.
This is sent as an individual patch in v2 because the other patches in
the [v1] series are either invalid or for different purpose in different
binding, so I think it'd be better to send them separately.

[v1]:
https://lore.kernel.org/all/20241025104548.1220076-4-fshao@chromium.org/

Changes in v2:
- specify '#sound-dai-cells' with const value
- update commit message

Thanks!

[1/1] ASoC: dt-bindings: maxim,max98390: Reference common DAI properties
      commit: 9b915776e0e6a2d185498077e0ebdb154a2751ac

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
