powerpc/85xx: Rework P2020DS pci_init_board to use common FSL PCIe code
Remove duplicated code in P2020DS 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: Li Yang <leoli@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
