sPAPR: Reenable EEH functionality on reboot

When rebooting the guest, some PEs might be in frozen state. The
contained PCI devices won't work properly if their frozen states
aren't cleared in time. One case running into this situation would
be maximal EEH error times encountered in the guest.

The patch reenables the EEH functinality on PEs on PHB's reset
callback, which will clear their frozen states if needed.
