[D18] usb1: add USB DRD support

Add USB DRD support on SoC USB1 interface. Host/Device detection is done by ID pin via usb-role-switch connector.

DRD mode is a reduced functionality OTG mode: in DRD operation, the controller mode (Host/Device) is decided based on the ID pin status. With the ID pin at ground the mode is Host and otherwise it is Device: once a cable plug is attached the controller selects the state and doesn't change it until the cable is unplugged.
