The Rust `Regulator` abstraction uses `NonNull` to wrap the underlying
`struct regulator` pointer. When `CONFIG_REGULATOR` is disabled, the C
stub for `regulator_get` returns `NULL`. `from_err_ptr` does not treat
`NULL` as an error, so it was passed to `NonNull::new_unchecked`,
causing undefined behavior.
Fix this by using a raw pointer `*mut bindings::regulator` instead of
`NonNull`. This allows `inner` to be `NULL` when `CONFIG_REGULATOR` is
disabled, and leverages the C stubs which are designed to handle `NULL`
or are no-ops.
