[PATCH v6 15/18] rust: platform: refactor to use `&raw mut`

[Antonio Hickey <contact@antoniohickey.com>]

Replacing all occurrences of `addr_of_mut!(place)`
with `&raw mut place`.

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