CS7500 Switch Support

[helixzz]

FYI, we've able to run ibswinfo.sh to query information on CS7500 (648x100G framed switch).
From the output we may identify the switch unit is acting as spine or leaf. However, the PSU status is wrong, as the CS7500 switch has a bunch of PSUs and these PSUs weren't bonded to specific switch units.
