Resolve most warnings from the 'sparse' static analysis tool for the arch/riscv codebase. This makes life easier for us as maintainers, and makes it easier for developers to use static analysis tools on their own changes.
This fourth version drops some patches that were in the previous versions, and restructures some of what was left. Much of this was based on feedback from Christoph Hellwig <hch@lst.de>, Luc Van Oostenryck <luc.vanoostenryck@gmail.com>, and Greentime Hu <greentime.hu@sifive.com>.
Applies on the current riscv fixes branch, which itself is based on v5.4-rc5. Tested on RV32 QEMU, RV64 QEMU, and the SiFive HiFive Unleashed board.
