According to the Odroid-N2 schematics, the micro-USB phy is powered
via a gpio-controlled regulator PWREN, updates the phy-supply to
correctly assign the power supply for usb2_phy.
Additionally, the USB3 combo port, which connects to the onboard
4-port USB hub, is powered by the main VCC_5V rail. Updated the
phy-supply to correctly assign vcc_5v for the USB controller node.
These changes ensure accurate power supply configuration for
USB components, improving hardware compatibility and power management.
