ASoC: dt-bindings: maxim,max98390: Reference common DAI properties

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]+'
