[PATCH] dt-bindings: soundwire: qcom: Document v2.1.0 version of IP block

[Krzysztof Kozlowski]

All Qualcomm SoC Soundwire controllers are version-detectable (even
1.x), however certain unidentified quirks might be potentially needed,
so document v2.1 version used on Qualcomm SM8650 and SM8750 SoCs,
fallbacking to v2.0.
