rust: driver-core: use "kernel vertical" style for imports

[ Upstream commit 52563c665b0b0b39f319bee40ecc5e8f25b9050a ]

Convert all imports to use "kernel vertical" style.

With this, subsequent patches neither introduce unrelated changes nor
leave an inconsistent import pattern.

While at it, drop unnecessary imports covered by prelude::*.
