Some not critical changes, and a bit more testing was done
(on ux164 - including card with an extra bridge, thanks to Michal).

Changes from bridges-2.4.0t11-rth:
- Disable devices before changing BARs
- Handle bridges not supporting IO forwarding
- Handle bridges with their own IO ports and/or memory
- Set cache line and default latency for all devices
- Updated comment for empty IO/memory ranges case

Diffs against bridges-2.4.0t11-rth and pristine 2.4.0-test11 attached.

Ivan.
