This series adds support for the role-switch-default-mode binding, to configure
the controller default mode, when the role is USB_ROLE_NONE.

This has been tested on STM32MP15 DK2 board, with:
 &usbotg_hs {
 	phys = <&usbphyc_port1 0>;
 	phy-names = "usb2-phy";
 	usb-role-switch;
 	dr_mode = "peripheral";
 	role-switch-default-mode = "peripheral";
 	status = "okay";
 }
