arm64: dts: marvell: add description for the Armada 8040 dev board

This commit adds a Device Tree description for the Marvell Armada 8040
Development Board. It features a quad-core Cortex A72 Armada 8040 SoC,
with a large number of peripherals: dual Gigabit, dual 10 GBit, 6 PCIe
interfaces, 6 SATA ports, 4 USB 3.0 ports, and more.

Only a subset of the functionalities are supported so far, and
additional features will be progressively enabled in the future.
