[PATCH v2 1/8] rust: dma: use "kernel vertical" style for imports

[Danilo Krummrich]

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::*.
