The UDC driver for this beautiful USB controller is mostly rewritten from scratch. USB Pad Calibration and clock handling are copied from the usb_dc_sam0 driver. The driver uses multipacket transfers for all endpoints except the OUT control endpoint. The OUT control endpoint has a buffer that is always mapped to the endpoint buffer register so that it always has a valid buffer. The driver provides up to 7 IN and 7 OUT endpoints that support any type of transfer. Double buffering is not used, for the possible case of isochronous transfers some changes would be required in the future. Signed-off-by: Johann Fischer <johann.fischer@nordicsemi.no>
