Add support for the nwp serial device which is connected to a DCR bus. It uses the of_serial device driver to determine necessary properties from the device tree. The supported device is added as serial port number 85. NWP stands for network processor and it is part of the QPACE - Quantum Chromodynamics Parallel Computing on the Cell Broadband Engine project. The implementation is a lightweight uart implementation with the focus to consume as little resources as possible and it is connected to a DCR bus.
