Subject: [PATCH v2 3/4] arm64: dts: qcom: sm8550: move Soundwire pinctrl to its nodes

Pin configuration for Soundwire bus should be set in Soundwire
controller nodes, not in the associated macro codec node.  This
placement change should not have big impact in general, 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.
