Subject: [PATCH] arm64: dts: qcom: sm8450: disable by default Soundwire and VA-macro

Soundwire is a bus and VA-macro requires a supply, thus both are
expected to be explicitly enabled and populated by board DTS.  The
HDK8450 already enables Soundwire devices, except swr4 which as a result
of this commit will stay disabled.
