dt-bindings: sound: fsl,qmc-audio: Add support for multiple QMC channels per DAI

The QMC audio uses one QMC channel per DAI and uses this QMC channel to
transmit interleaved audio channel samples.

In order to work in non-interleave mode, a QMC audio DAI needs to use
multiple QMC channels. In that case, the DAI maps each QMC channel to
exactly one audio channel.

Allow QMC audio DAIs with multiple QMC channels attached.
