arm64: dts: qcom: x1e80100-qcp: Add FSUSB42 USB switches

Browse Source 
Unlike most X1E boards, the QCP does not have Parade PS8830 retimers on the
three USB-C ports. Instead, there are FSUSB42 USB switches for each port
that handle orientation switching for the SBU lines. The overall setup is
similar to the gpio-sbu-mux defined for sc8280xp-crd and the ThinkPad X13s.
