[PATCH] ASoC: dt-bindings: an7581-afe: add support for reset and secondary IRQ conf

[Christian Marangi]

Driver got support for configuring the secondary IRQ configuration to
support full-duplex mode (playback and capture at the same time) and also
to reset via the dedicated SoC reset line.

Add the property to support it and make update the example accordingly for
a more specific register mapping.

Also add the missing #sound-dai-cells property required for the generic
sound node structure.

Previous register node definition doesn't prevent normal execution of the
AFE driver as the additional IRQ register is placed at the end of all the
previous AFE configurations.
