hw/rdma: Deprecate the pvrdma device and the rdma subsystem
This subsystem is said to be in a bad shape (see e.g. [1], [2] and [3]), and nobody seems to feel responsible to pick up patches for this and send them via a pull request. For example there is a patch for a CVE-worthy bug posted more than half a year ago [4] which has never been merged. Thus let's mark it as deprecated and finally remove it unless somebody steps up and improves the code quality and adds proper regression tests.
