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.
