Subject: [PATCH v8 7/9] rust: platform: Set `OF_ID_TABLE` default to `None` in `Driver` trait

Provide a default value of `None` for `Driver::OF_ID_TABLE` to simplify
driver implementations.

Drivers that do not require OpenFirmware matching no longer need to
import the `of` module or define the constant explicitly.

This reduces unnecessary boilerplate and avoids pulling in unused
dependencies.
