platform: Add OpenPiton platform support
OpenPiton is a research platform from Princeton University [1].
"OpenPiton is the world's first open source, general purpose,
multithreaded manycore processor. It is a tiled manycore
framework scalable from one to 1/2 billion cores."
Add OpenSBI support for OpenPiton. As it is based on ariane core,
it reuses the platform code from arine project.
