You need to select USB_ROLE_SWITCH in Kconfig:
diff --git a/drivers/usb/dwc3/Kconfig b/drivers/usb/dwc3/Kconfig
index 1a0404fda596..3a0cb9f1f38a 100644
--- a/drivers/usb/dwc3/Kconfig
+++ b/drivers/usb/dwc3/Kconfig
@@ -42,6 +42,7 @@ config USB_DWC3_DUAL_ROLE
bool "Dual Role mode"
depends on ((USB=y || USB=USB_DWC3) && (USB_GADGET=y || USB_GADGET=USB_DWC3))
depends on (EXTCON=y || EXTCON=USB_DWC3)
+ select USB_ROLE_SWITCH
help
This is the default mode of working of DWC3 controller where
both host and gadget features are enabled.
