Sync the default configuration of Armada-8040-DB with Marvell u-boot-2015 standard configuration "A" for the same board. The standard configuration "A" enables 2 PCIe slots on CP0 and 3 PCIe slots on CP1. This is the main configuration used for u-boot and Linux tests. This patch also re-arranges the DTS file entries by grouping all nodes related to CP0 and CP1.
