PCI: Do not enable AtomicOps by RCiEPs
Since Root Complex Integrated Endpoints (RCiEPs) attach to a bus that has
no bridge device describing the Root Port, the capability to complete
AtomicOps requests cannot be determined with PCIe methods.
Change default of pci_enable_atomic_ops_to_root() to not enable AtomicOps
requests on RCiEPs.
As far as we know, there are no RCiEPs that need AtomicOps (see Link
below).
