arm64: mvebu: Add basic support for the Turris Mox board
This adds basic support for the Turris Mox board from CZ.NIC, which is currently being crowdfunded on Indiegogo. Turris Mox is as modular router based on the Armada 3720 SOC (same as EspressoBin). The basic module can be extended by different modules. The device tree binary for the kernel can be dependent on which modules are connected, and in what order. Because of this, the board specific code creates in U-Boot a variable called module_topology, which carries this information.
