[U-Boot] [PATCH] fdt: pci: Permit use of reg property for setting device address

[Simon Glass]

In commit a62e84d the old functionality of obtaining a PCI address from the
'reg' property was lost. Add it back, so we can support both a compatible
string list and a 'reg' property.

This patch fixes PCIe ethernet on Tegra boards.
