The renesas usbhs driver calls extcon_get_edev_by_phandle(), which is defined in drivers/extcon/extcon-class.c, and that can be a loadable module. If the extcon-class support is disabled, usbhs will work correctly for all devices that do not need extcon.
However, if extcon-class is a loadable module, and usbhs is built-in, the kernel fails to link. In order to solve that, we need a Kconfig dependency that allows extcon to be disabled but does not allow usbhs built-in if extcon is a module.
