[PATCH v3 06/11] rust: of: replace `core::mem::zeroed` with `pin_init::zeroed`

[Benno Lossin <lossin@kernel.org>]

All types in `bindings` implement `Zeroable` if they can, so use
`pin_init::zeroed` instead of relying on `unsafe` code.

If this ends up not compiling in the future, something in bindgen or on
the C side changed and is most likely incorrect.
