Subject: [PATCH 21/23] arm64: dts: qcom: sm8550: add sound prefix for wsa2

From: Srinivas Kandagatla <srinivas.kandagatla@....qualcomm.com>

WSA and WSA2 are two instances of WSA codec macro, this can lead
dupicate dapm widgets and mixers resulting in failing to probe
soundcard if both of these instances are part of the dai-link.

Correct way to address this is to add sound-name-prefix to WSA2
instances to avoid such confilcting mixers and dapm widgets.
