USB: atmel uaba: Adding invert vbus_pin
Adding vbus_pin_inverted so that the usb detect pin can be active high or low depending on HW implementation also replaced the gpio_get_value(udc->vbus_pin); with a call to vbus_is_present(udc); This allows the driver to be loaded and save about 0,15W on the consumption.
