[PATCH] D117199: [RISCV] Add missing namespace (NFC)

[Yeting Kuo via Phabricator via cfe-commits]

fakepaper56 added a comment.

The main reason I want to add the prefix "llvm::" is all None in the files are "llvm::None" form. But also it is more feasible when we want to add a variable name 'None' in the file.
