Doug Brown 5e8224e35e Add USB CDC serial port code
This implements a USB CDC serial port using the Nuvoton USBD driver. The
USB handling is based on Nuvoton's BSP sample code, especially the IRQ
handlers and descriptor buffer configuration. The descriptors have been
adapted to be similar to the AVR version, and RX/TX functions have been
written to implement an API closer to LUFA, which is what the SIMM
programmer common code needs.
