dev: Added new LupIO-RNG device
This device is a random number generator that uses the Mersenne
Twister in order to provide the system with a set of random
numbers. It is implemented as a BasicPioDevice, and has both
read and write capabilities.
The following are the specifications regarding the LupIO-RNG:
