[PATCH 1/13] dt-bindings: sound: Add Qualcomm QAIF DAI ID header

[Harendra Gautam <harendra.gautam@oss.qualcomm.com>]

Add a dt-bindings header for the Qualcomm Audio Interface (QAIF) controller
DAI IDs. This provides shared constants for devicetree sound-dai references
and QAIF aif-interface reg values instead of using raw numeric IDs.
