lib: dai: Expose Zephyr DAI device retrieval function

This patch exposes the function to retrieve a pointer to the Zephyr device structure for a DAI of a given type and index. Previously, the function `dai_get_zephyr_device` was static and only usable within `dai.c`. By introducing `dai_get_device`, other parts of the SOF codebase can now access the Zephyr DAI device pointers, facilitating integration with Zephyr native DAI drivers.
