Johann Fischer c8eaa11a0b drivers: udc: add new UDC driver for SAM0 USB controller
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.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
