Subject: [PATCH v9 7/7] arm64: dts: qcom: qrb5165-rb5: Switch on TCPM orientation-switch for usb_1_qmpphy

Switch on USB orientation-switching for usb_1_qmp via TCPM. Detecting the
orientation switch is required to get the PHY to reset and bring-up the PHY
with the CC lines set to the appropriate lane.
