IB/mad: Add partial Intel OPA MAD support
This patch is the first of 3 which adds processing of OPA MADs
1) Add Intel Omni-Path Architecture defines
2) Increase max management version to accommodate OPA
3) update ib_create_send_mad
If the device supports OPA MADs and the MAD being sent is the OPA base
version alter the MAD size and sg lengths as appropriate
