[IA64] respect ACPI producer/consumer flag for PCI root bridges

Address space resources for ACPI devices have a producer/consumer
flag.  All devices "consume" the indicated address space.  If the
resource is marked as a "producer", the range is also passed on
to child devices.

We currently ignore this flag when setting up MMIO and I/O port
windows for PCI root bridges, so we could mistakenly interpret
a "consumed-only" range, like CSR space for the device itself,
as a window that is routed to children.
