Support for HDR and NDR switches

[tabaer]

We have found that the ibswinfo.sh script handles HDR (MQM8790-HS2F) and NDR (MQM9790-NS2F) IB switches just fine, except that only 9 fan speeds are reported instead of 14 (6x2 + 2 PSUs) on the HDR switches and 16 (7x2 + 2 PSUs) on the NDR switches. We have not yet been able to determine a cause for this.

I can confirm the issue, but don't really have a good explanation for it either. :\
