When CONFIG_DM_USB=y the various usb functions are available regardless of any controller drivers being enabled, so always the usb function prototypes when CONFIG_DM_USB=y.
This fixes compile warnings due to missing prototypes on ARCHs where the ARCH Kconfig always enables CONFIG_DM_USB and various usb drivers. One could argue that in the case of no controllers CONFIG_DM_USB should not be set, but this problem is typically seen during bringup of boards which do actually have usb controllers.
