pwm: Fix Rust formatting

We do our best to keep the repository `rustfmt`-clean [1], thus run the
tool to fix the formatting issue.

A trailing empty comment [2] is added in order to preserve the wanted
style for imports (otherwise the tool will compact the first two items).

Fixes: d8046cd50879 ("rust: pwm: Add complete abstraction layer")
Fixes: 7b3dce814a15 ("rust: pwm: Add Kconfig and basic data structures")
Fixes: e03724aac758 ("pwm: Add Rust driver for T-HEAD TH1520 SoC")
