Subject: [PATCH v6 13/18] rust: time: hrtimer: refactor to use `&raw const`

Replacing all occurrences of `addr_of!(place)` with
`&raw const place`.

This will allow us to reduce macro complexity, and improve consistency
with existing reference syntax as `&raw const` is similar to `&` making
it fit more naturally with other existing code.
