rust: remove unnecessary Cargo.toml metadata

Some items of Cargo.toml (readme, homepage, repository) are
only present because of clippy::cargo warnings being enabled in
rust/hw/char/pl011/src/lib.rs.  But these items are not
particularly useful and would be all the same for all Cargo.toml
files in the QEMU workspace.  Clean them up.
