pciexp_device: Propagate above-4G flag to all hotplug devices
The `IORESOURCE_ABOVE_4G` flag was only explicitly set for our dummy
device that reserves resources behind a hotplug port. The current re-
source allocator implicitly extends this to all devices below the port,
including real ones. Let's make that explicit, so future changes to the
allocator can't break this rule.
