This change allows us to support more devices in a backwards-compatible manner. The first IB_UVERBS_MAX_DEVICES keep the same major/minor device numbers that they've always had. If there are more than IB_UVERBS_MAX_DEVICES, we then dynamically request a new major device number (new minors start at 0). This change increases the maximum number of HCAs to 64 (from 32).
