ARM: dts: msm: Enable USB VBUS detection on APQ8084 Liquid

APQ8084 Liquid routes USB0 port to a TPD4S214 chip to do VBUS
detection. This will enable USB cable connect/disconnect detection
on this platform. This differs from CDP/MTP targets which have an
SMB349 charger IC and is handled by a separate driver.
