dt-bindings: sound: qcom,sm8250: allow TDM slot properties

Browse source

Allow standard dai-tdm-slot-* properties in the CPU and codec child
nodes of a DAI link.

The QCOM machine driver parses these child nodes to configure TDM slots
on the active CPU and codec DAIs.  The properties are already defined by
the common tdm-slot binding, but qcom,sm8250.yaml currently rejects them
because the CPU and codec child nodes set additionalProperties: false.

Permit dai-tdm-slot-num, dai-tdm-slot-width and dai-tdm-slot-[rt]x-mask
there so boards using TDM backends can describe the slot layout without
schema warnings.
