IB/ehca: HW level, HW caps and MTU autodetection
In preparation for support of new eHCA2 features, change adapter probing:
- Hardware level is changed to encode major and minor chip version
- Hardware capabilities are queried from the firmware
- The maximum MTU is queried from the firmware instead of assuming a
fixed value
