Convert `use` imports to vertical layout for better readability and
maintainability.

Came across a recent commit bc58905eb07 ("samples: rust_misc_device: use
vertical import style") and found a few more locations that could
benefit from this cleanup. No functional changes.

Separating out patches per-subsystem as per the review feedback in [0].

Tested via:

    $ make LLVM=1 rustfmtcheck || echo "fail"
    $
