This patch adds a new child node `abox_ipc_generic` under the
`abox_generic` node for ExynosAuto v920. The ABOX IPC Generic
driver handles inter-processor communication (IPC) between
the ABOX DSP and host SoC using IRQs.
The node includes configuration for the number of IRQ channels
used for IPC routing. This allows SoC-specific subsystems to
send and receive messages through the ABOX generic audio stack.
