[PATCH v2 2/4] rust: i2c: Update ARef and AlwaysRefCounted imports to use sync::aref

Update call sites in `i2c.rs` to import `ARef` and
`AlwaysRefCounted` from `sync::aref` instead of `types`.

This aligns with the ongoing effort to move `ARef` and
`AlwaysRefCounted` to sync.

v1 -> v2:

Used the direct module name instead of including the path again,
re-worded the commit title to rust: i2c: and
carry-forwarded the Acked-by tag.
