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

Changes in v4:
- Check compatible string 12th byte against '\0'
Acked-by: Simon Glass sjg@chromium.org
Changes in v3:
- Fixed a typo: parant -> parent
- Return better error code in fdtdec_get_pci_addr()
- Add some debug output in fdtdec_get_pci_addr()
- Reuse variable 'len' instead of creating a new one 'l'
- Check compatible string length and existence of '.'
- Using simple_strtol() directly on the compatible sub-string
- Change variable 'bn' to 'barnum' which is self-documenting
Changes in v2:
- New patch to add several apis to decode pci device node
