[PATCH v2] ASoC: dt-bindings: maxim,max98390: Reference common DAI properties

[Fei Shao <fshao@xxxxxxxxxxxx>]

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@xxxxxxxxxxxx/

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