sPAPR: Don't enable EEH on emulated PCI devices

Browse Source 
There might have emulated PCI devices, together with VFIO PCI
devices under one PHB. The EEH capability shouldn't enabled
on emulated PCI devices.

The patch returns error when enabling EEH capability on emulated
PCI devices by RTAS call "ibm,set-eeh-option".
