[PATCH 3/3] ASoC: dt-bindings: qcom, wcd934x: Allow usage as IFD device

[Krzysztof Kozlowski]

The WCD9340 audio codec appears on Slimbus twice: as IFD device without
properties and the actual audio-codec referencing the former via
wcd9340_ifd.  Allow in the binding both versions to fix several warnings
like:

  sdm850-samsung-w737.dtb: ifd at 0,0: 'reset-gpios' is a required property
  sdm850-samsung-w737.dtb: ifd at 0,0: 'slim-ifc-dev' is a required property
  sdm850-samsung-w737.dtb: ifd at 0,0: 'interrupt-controller' is a required property

oneOf: interrupts-extended|interrupts is needed to avoid dtschema
limitation.
