Subject: [PATCH] FROMLIST: arm64: dts: qcom: lemans: enable EUD support

Add the EUD controller node in lemans.dtsi and update the USB HS
endpoint routing on lemans-evk to pass through EUD instead of linking
the connector directly to usb_0_dwc3_hs.

Wire the OF graph endpoints between the connector, EUD and DWC3 HS
controller to enable the EUD path on lemans EVK.
