Nios 2 target code ownership

Dear LLVM community,

Currently nobody is appointed as code owner for Nios 2 target. Since I've already developed a part of it and I'm planning to do more development in this area in coming weeks, I would like to volunteer myself to become code owner for this target. Please let me know if you have anything against, otherwise I'll add myself to CODE_OWNERS.TXT (I'll wait till the end of this week for any comments).

Kind regards,
Mateusz Belicki
