bindings: usb: qcom,dwc-usb3-msm: Add vbus_dwc3-supply property to bindings

Browse Source 
The vbus_dwc3-supply property in the device tree manages
the 5V for USB host mode.

It is designed for platforms with hardware VBUS detection
based on a GPIO regulator, allowing the system to control
the USB port power supply, enabling or disabling
it in suspend/resume cases.
