commit a62e84d7b1 incorrectly changed the tegra pci code to the
new fdtdec pci helpers. To get the device index of the root port, the
"reg" property should be parsed from the dtb (as was previously the
case).
With this patch i can successfully network boot my jetson tk1

This commit adds several APIs to decode PCI device node according to
the Open Firmware PCI bus bindings, including:
- fdtdec_get_pci_addr() for encoded pci address
- fdtdec_get_pci_vendev() for vendor id and device id
- fdtdec_get_pci_bdf() for pci device bdf triplet
- fdtdec_get_pci_bar32() for pci device register bar

(Include <pci.h> in fdtdec.h and adjust tegra to fix build error)
Add support for the PCIe controller found on some generations of Tegra.
Tegra20 has 2 root ports with a total of 4 lanes, Tegra30 has 3 root
ports with a total of 6 lanes and Tegra124 has 2 root ports with a total
of 5 lanes.
This is based on the Linux kernel driver, originally submitted upstream
by Mike Rapoport.
