mpc83xx: Add support for MPC83xx PCI-E controllers
This patch adds support for MPC83xx PCI-E controllers in Root Complex mode. The patch is based on Tony Li and Dave Liu work[1]. Though unlike the original patch, by default we don't register PCI-E buses for use in U-Boot, we only configure the controllers for future use in other OSes (Linux). This is done because we don't have enough of spare BATs to map all the PCI-E regions. To actually use PCI-E in U-Boot, users should explicitly define CONFIG_83XX_GENERIC_PCIE_REGISTER_HOSES symbol in the board file. And only then U-Boot will able to access PCI-E, but at the cost of disabled address translation.
