[PATCH v3 4/4] of: address: kill of_node_is_pcie()

[Alex Elder <elder@riscstar.com>]

The of_bus->match function for the "PCI" bus type is fairly liberal
in what it accepts as a PCI bus devicetree node.  If a node has no
device_type property, it even allows a node named "pcie@" to be
accepted as represnting a devicetree bus, though it issues a warning
in that case.

A recent PCI commit introduced of_pci_verify_node().  When a PCI
device is added, if it has a devicetree node, that function checks
its device_type property.  For PCI bridge devices, if there is no
device_type property (value "pci"), a warning is issued.

That warning duplicates the warning made by of_node_is_pcie(), and
there's no point in that.  Avoid the second (OF) warning by just
checking the node name directly in of_bus_pci_match().

That leaves of_node_is_pcie() unused, so get rid of it.
