The vbus rise & fall interrupts are used to enable and disable U3 function of device automatically, this cause some issues when class driver is initialized as deactivated, and will skip over software-controlled connect by pullup(), but UDC wants to keep disconnect until usb_gadget_activate() is called which calls pullup() if needed. So we disable vbus rise & fall interrupts and just use pullup() to enable & disable U3 function, and reset mtu3 state when disconnect instead when vbus fall.
