Subject: [PATCH V3 5/7] arm64: dts: qcom: sc7280: Add EUD dt node and dwc3 connector

Add the Embedded USB Debugger(EUD) device tree node. The
node contains EUD base register region and EUD mode
manager register regions along with the interrupt entry.
Also add the connector to EUD which is mapped as the child
of dwc3. The connector is attached to EUD via port. Also add
the role-switch property to dwc3 node.
