This adds support for the Turris Mox board from CZ.NIC. Turris Mox is as modular router based on the Armada 3720 SOC (same as EspressoBin). The basic module can be extended by different modules. When those modules are connected, U-Boot shall patch this device-tree by enabling nodes corresponding to those modules.
