audio: dai-zephyr: Set source/destination address adjustment

Some DMACs (e.g: NXP's EDMA) can automatically adjust the source and
destination addresses upon transfer completion. As such, we need to
indicate how the adjustment should be performed. In the case of playback,
the source address should be decremented, while in the case of capture,
the destination address should be decremented.
