RDMA/include: Replace license text with SPDX tags The header files in RDMA subsystem are dual licensed and can be described by simple SPDX tag, so replace all of them at once together with making them use the same coding style for header guard defines.

IB/SA: Add OPA addr header When importing the patch 57520751445b (IB/SA: Add OPA path record type), a new header file should have been added to the repo as part of the patch. However, as the patch didn't apply cleanly using git am, I instead used patch manually, and followed that up with git add -u, which misses new files. This adds the new file back in.
