PCI: xgene: Revert "PCI: xgene: Fix IB window setup"
Commitc7a75d0782
("PCI: xgene: Fix IB window setup") tried to fix the damages that6dce5aa59e
("PCI: xgene: Use inbound resources for setup") caused, but actually didn't improve anything for some plarforms (at least Mustang and m400 are still broken). Given that6dce5aa59e
has been reverted, revert this patch as well, restoring the PCIe support on XGene to its pre-5.5, working state. Link: https://lore.kernel.org/r/YjN8pT5e6/8cRohQ@xps13.dannf Link: https://lore.kernel.org/r/20220321104843.949645-3-maz@kernel.org Fixes:c7a75d0782
