It did ensure correct timing for rb2 so YMMV :D

because macro
codec is a clock provider for Soundwire controller, thus its devices is
probed first. However it will have impact for disabled Soundwire buses,
e.g. WSA2, because after this change the pins will be left in default
state.

We also follow similar approach in newer SoCs, like Qualcomm SM8650.
