sPAPR: Revert don't enable EEH on emulated PCI devices

This reverts commit 7cb18007 ("sPAPR: Don't enable EEH on emulated
PCI devices") as rtas_ibm_set_eeh_option() isn't the right place
to check if there has the corresponding PCI device for the input
address, which can be PE address, not PCI device address.
