The G12A USB2 OTG capable PHY uses a 8bit large UTMI bus, and the OTG controller gets the PHY but width by probing the associated phy.
By default it will use 16bit wide settings if a phy is not specified, in our case we specified the phy, but not the phy-names.
The dwc2 bindings specifies that if phys is present, phy-names shall be "usb2-phy".
Adding phy-names = "usb2-phy" solves the OTG PHY bus configuration.
