Many lints that default to allow can be helpful in detecting bugs or
keeping the code style homogeneous. Add them liberally, though perhaps
not as liberally as in hw/char/pl011/src/lib.rs. In particular, enabling
entire groups can be problematic because of bitrot when new links are
added in the future.
For Clippy, this is actually a feature that is only present in Cargo
1.74.0 but, since we are not using Cargo to *build* QEMU, only developers
will need a new-enough cargo and only to run tools such as clippy.
The requirement does not apply to distros that are building QEMU.
