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.
