pub const DEFAULT_DAI_INTERCONNECT_ELEMENT_ID: u64 = 1;

For devices with Codec or Dai drivers, there is only one DAI_INTERCONNECT entity. When a method requires us to address the interconnect by ID, we use element_id 1. Codec and Dai drivers that implement signalprocessing should not assign this ID to other elements.
