Merge #227

227: Add register-rs to the project list of new Cortex-A team r=andre-richter a=phil-opp

The crate is currently hosted under the rust-osdev organization: https://github.com/rust-osdev/register-rs. Moving it to the WG was part of the recently accepted [RFC for a Cortex-A team](#207 (comment)).

This PR follows the process outlined in https://github.com/rust-embedded/wg/blob/master/rfcs/0136-teams.md#adopting-projects.
