Danilo Krummrich 016267b521 rust: devres: add 'static bound to Devres<T>
Devres::new() registers a callback with the C devres subsystem via
devres_node_add(). If the Devres is leaked (e.g. via
core::mem::forget(), which is safe), its Drop impl never runs, and the
devres release callback will revoke the inner Revocable on device
unbind, which drops T in place. If T contains non-'static references,
those may be dangling by that point.

Add a 'static bound to prevent storing types with borrowed data in
Devres.
