[PATCH 0/2] ARM/PCI: Make I/O port space optional

[Bjorn Helgaas]

Currently we always require an I/O port resource for PCI host bridges.  Even
if the bridge doesn't actually support I/O port space, we add a default I/O
resource for it.

These patches make I/O port space optional on ARM.  Comments welcome.

If these look OK, I'll fold them into the series at [1], where they should
fix a resource conflict [2] in the R-Car driver.
