Add supprot for Marvell platforms based on Armada-37xx SoC. This includes support for the official Armada-3720 modular development board and EspressoBin community board. The Armada-37xx SoC contains dual Cortex-A53 Application CPU, single secure CPU (Cortex-M3) and the following interfaces: - SATA 3.0 - USB 3.0 and USB 2.0 - PCIe - SDIO (supports boot from eMMC) - SPI - UART - I2c - Gigabit Ethernet Signed-off-by: Konstantin Porotchkin <kostap@marvell.com>
