IRONside calls are remote procedure calls which comprise the runtime interface of Nordic IRONside SE. They are realized using a simple IPC mechanism. A local domain (client) issues requests to the server by exchanging data in shared memory, which is divided into evenly sized buffers. The client selects a buffer, writes a request into it, and sends it to the server. The server processes that request and writes a response into the same buffer before returning it to the client. This patch adds the initial client-side implementation on top of MBOX. It features cache management and a blocking alloc/dispatch/release API for synchronous, zero-copy transfers. A new devicetree binding is added to support this implementation. It is patterned after the `zephyr,ipc-*` bindings, where each node associates a pair of mailboxes and a shared memory region.
