[PATCH v5 12/17] rust: net: phy: refactor to use `&raw [const|mut]`

[Antonio Hickey]

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.
