Yinghai Lu d63e2e1f3d sparc/PCI: Clip bridge windows to fit in upstream windows 
Every PCI-PCI bridge window should fit inside an upstream bridge window
because orphaned address space is unreachable from the primary side of the
upstream bridge.  If we inherit invalid bridge windows that overlap an
upstream window from firmware, clip them to fit and update the bridge
accordingly.
