PCI: x86: use generic pci_enable_resources()
Use the generic pci_enable_resources() instead of the arch-specific code. Unlike this arch-specific code, the generic version: - checks for resource collisions with "!r->parent" Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
