rGedbbf26e2650: pci/n1sdp: Disable HotPlug
Summary

Work around an issue when HotPlug is enabled where pcib3 and pcib5
continuously report the following:

pcib3: HotPlug interrupt: 0x30
pcib3: Command Completed
pcib3: HotPlug interrupt: 0x30
pcib3: Command Completed
...

As a workaround disable HotPlug on the N1SDP as it's unlikely anyone
will depend on it.
