Dan Horák 1ddbacb67f syscon: Implement a register for storing git hash info
It also stores the dirty status so that's known.

This does some Makefile tricks so that we only rebuild when the git
hash changes. This avoids rebuilding the world every time we run
make.

Also adds fusesoc generator, so that should continue to work as
before.
