The pnv_phb->initialized flag is an odd beast. It was added back in 2012 in
commit db1266c85261 ("powerpc/powernv: Skip check on PE if necessary") to
allow devices to be enabled even if the device had not yet been assigned to
a PE. Allowing the device to be enabled before the PE is configured may
cause spurious EEH events since none of the IOMMU context has been setup.

I'm not entirely sure why this was ever necessary. My best guess is that it
was an workaround for a bug or some other undesireable behaviour from the
PCI core. Either way, it's unnecessary now since as of commit dc3d8f85bb57
("powerpc/powernv/pci: Re-work bus PE configuration") we can guarantee that
the PE will be configured before the PCI core will allow drivers to bind to
the device.

Applied to powerpc/next.
