usb: dwc3: fix the glue drivers using the nop phy
The reset_gpio member of the usb_phy_gen_xceiv_platform_data structure needs the have negative value or phy-generic's probe will fail unless DT is used. 0 is a valid gpio number. This fixes an issue where phy-generic fails to probe with message: "usb_phy_gen_xceiv.0: Error requesting RESET GPIO 0".
