    Documentation PCI: Reformat RMW ops documentation

    Extract the list of RMW protected PCIe Capability registers into a
    bullet list to make them easier to pick up on a glance. An upcoming
    change is going to add one more register among them so it will be much
    cleaner to have them as bullets.
