[PATCH v2 25/29] arm/PCI: convert to pci_scan_root_bus() for correctroot bus resources

From: Bjorn Helgaas
Date: Fri Oct 14 2011 - 00:30:10 EST

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
resource fixups. This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.
