Remove usages of raw register manipulation outside of PAC crates

We currently have duplicates of these reg functions where the svd's don't have enough info, and we have to resort back to raw register writes. E.g: https://github.com/search?q=repo%3Aesp-rs%2Fesp-hal%20reg_set&type=code. We should cleanup...
