With all the bors thing going on, I've been reading a bit about merge queues etc. and noticed that some of our workflows still use outdated/deprecated actions. This PR fixes this.

129: PLIC peripheral r=romancardenas a=romancardenas

Same as #125 (closing right now) but with a clean commit history. I've been playing around with this implementation and detected nice-to-have features and boring patterns that could be implemented using macros. Pointers to repos that are already working with it:

- [`e310x` PAC](https://github.com/greenlsi/e310x)
- [`e310x-hal` HAL](https://github.com/greenlsi/e310x-hal)
- [`hifive1` BSP](https://github.com/romancardenas/hifive1) with an illustrative [example](https://github.com/romancardenas/hifive1/blob/master/examples/interrupt.rs

123: Added clippy to the CI workflow r=almindor a=romancardenas

I've been working with this crate for a while and noticed that it didn't include clippy as part of the CI process. This PR checks that clippy does not trigger any warning for new contributions. I also ran `cargo clippy --fix` to "fix" the crate.

If you think this is useful, I can adapt other repos (e.g., riscv-rt or e310x). Cheers!
