[PATCH 6/9] ASoC : dt-bindings: sound: Add binding for ABOX IPC Generic

This patch updates the existing samsung,exynosauto.yaml schema to
describe the ABOX IPC Generic child node. This node represents
a virtual IPC interface used by the ABOX audio subsystem to
communicate with SoC-specific hardware using shared IRQ channels.
The schema describes the `samsung,num-irq` property and allows
integration of the IPC node under `abox_generic`.
