RDMA/amso1100: Deprecate the amso1100 driver and move to staging

The HW hasn't been sold since 2005, and the SW has definite bit rot.
Its time to remove it.  So move it to staging for a few releases and
then remove it after that.

- * Verbs Request Objects:
- *
- * VQ Request Objects are allocated by the kernel verbs handlers.
- * They contain a wait object, a refcnt, an atomic bool indicating that the
- * adapter has replied, and a copy of the verb reply work request.
- * A pointer to the VQ Request Object is passed down in the context
- * field of the work request message, and reflected back by the adapter
- * in the verbs reply message.  The function handle_vq() in the interrupt
- * path will use this pointer to:
- * 	1) append a copy of the verbs reply message
- * 	2) mark that the reply is ready
- * 	3) wake up the kernel verbs handler blocked awaiting the reply.
- *
- *
- * The kernel verbs handlers do a "get" to put a 2nd reference on the
- * VQ Request object.  If the kernel verbs handler exits before the adapter
- * can respond, this extra reference will keep the VQ Request object around
- * until the adapter's reply can be processed.  The reason we need this is
- * because a pointer to this object is stuffed into the context field of
- * the verbs work request message, and reflected back in the reply message.
- * It is used in the interrupt handler (handle_vq()) to wake up the appropriate
- * kernel verb handler that is blocked awaiting the verb reply.
- * So handle_vq() will do a "put" on the object when it's done accessing it.
- * NOTE:  If we guarantee that the kernel verb handler will never bail before
- *        getting the reply, then we don't need these refcnts.
- *
- *
- * VQ Request objects are freed by the kernel verbs handlers only
- * after the verb has been processed, or when the adapter fails and
- * does not reply.
- *
- *
- * Verbs Reply Buffers:
- *
- * VQ Reply bufs are local host memory copies of a
- * outstanding Verb Request reply
- * message.  The are always allocated by the kernel verbs handlers, and _may_ be
- * freed by either the kernel verbs handler -or- the interrupt handler.  The
- * kernel verbs handler _must_ free the repbuf, then free the vq request object
- * in that order.
