Subject: [PATCH v6 3/4] arm64: dts: qcom: qcs615: add venus node to
 devicetree

Add the venus node to the devicetree for the qcs615 platform to enable
video functionality. The qcs615 platform currently lacks video
functionality due to the absence of the venus node. Fallback to sc7180 due
to the same video core.
