Hum, I was supposed to use this in arch/arm/mach-mvebu/ to make sure
that PCI I/O regions are mapped strongly-ordered. We're indeed doing it
for PCI mem regions, but we never did it for PCI I/O regions. I
remember there has been some discussions about this, but I don't
remember the outcome, and whether it has affected the fact that mapping
PCI I/O regions strongly-ordered for mach-mvebu was never merged.
