dai-zephyr: zero unused dai_config members

serhiy-katsyuba-intel · lgirdwood · commit 505e20117ec7 · 2026-02-20T14:58:04.000Z
This prevents initializing unused members of struct dai_config with
random garbage from the stack. In case some Zephyr DAI driver uses such
an uninitialized member, it's better to have a bug with stable
reproduction than a random one.
