Add device_type property for the pcie devicetree nodes
in sun.
This is needed to make sure that the pcie devicetree node
is associated with the pci bus when ranges property gets
parsed by the of/address.c driver.
And this change is mandatory for pci devicetree nodes with
the introduction of the following change in of/address.c
upstream commit <3d5089c4263d> "of/address: Add support
for 3 address cell bus".
Without this change, BAR address allocation failure will
happen as error logs below as the flags cell in ranges
property in devicetree will be read wrong.
