powerpc/85xx: Rework MPC8568MDS pci_init_board to use common FSL PCIe code
Remove duplicated code in MPC8568MDS board and utilize the common fsl_pcie_init_board(). We also now dynamically setup the LAWs for PCI controllers based on which PCIe controllers are enabled. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
