[PATCH v4 06/16] rust: platform: refactor to use `&raw [const|mut]`

[Antonio Hickey]

Replacing all occurrences of `addr_of!(place)` and `addr_of_mut!(place)`
with `&raw const place` and `&raw mut place` respectively.

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