PCI: Make pcie_find_root_port() work for Root Ports
Commit 6ae72bfa656e ("PCI: Unify pcie_find_root_port() and
pci_find_pcie_root_port()") broke acpi_pci_bridge_d3() because calling
pcie_find_root_port() on a Root Port returned NULL when it should return
the Root Port, which in turn broke power management of PCIe hierarchies.
Rework pcie_find_root_port() so it returns its argument when it is already
a Root Port.
[bhelgaas: test device only once, test for PCIe]
Fixes: 6ae72bfa656e ("PCI: Unify pcie_find_root_port() and pci_find_pcie_root_port()")
