This patch adds the PCM playback and capture device nodes as children of
the abox_generic audio controller for ExynosAuto v920.
Each PCM device is defined with a unique ID and an associated IRQ SW number
used for communication with the ADSP. These nodes include information such
as buffer size, ALSA DAI name prefix, and category type(e.g., deep_buffer).
The nodes are initially marked as "disabled" and can be enabled per board
(e.g., in the SADK .dts) as needed.
