Subject: [PATCH 2/2] arm64: dts: qcom: lemans: Add missing quirk for HS only USB controller

The PIPE clock is provided by the USB3 PHY, which is predictably not
connected to the HS-only controller. Add "qcom,select-utmi-as-pipe-clk"
quirk to  HS only USB controller to disable pipe clock requirement.

Fixes: de1001525c1a ("arm64: dts: qcom: sa8775p: add USB nodes")
