Add UCB RISCV support for architecture, soc, and emulation mainboard..
Works in the RISCV version of QEMU.
Note that the lzmadecode is so unclean that it needs a lot of work.
A cleanup is in progress.
We decided in Prague to do this as one thing, because it forms a nice case study
of the bare minimum you need to add to get a new architecture going in qemu.
