powerpc/85xx: Cleanup PCIe support on corenet_ds boards
Several changes on PCIe support on P3041DS/P4080DS/P5020DS boards: * Add support for "fsl,qoriq-pcie-v2.2" needed by P3041 & P5020 * Removed support for setting primary_phb_addr as we have no ISA need * Add PCI controller to of_platform_bus_probe (for EDAC) * Cleanup building w/SWIOTLB off on P4080DS (not stricly PCIe related) Signed-off-by: Kai.Jiang <Kai.Jiang@freescale.com> Signed-off-by: Laurentiu TUDOR <Laurentiu.Tudor@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
