The PinePhone has a Bluetooth chip with its PCM interface connected to AIF3. Add the DAI link so headeset audio can be routed in hardware. Even though the link is mono, configuring the link for 2 slots is required for compatibility with AIF2, which also uses 2 slots, and which shares clock dividers with AIF3. Using equal clock frequencies allows the modem and headset to be used at the same time.
