armv8/ls1043ardb: Add LS1043ARDB board support

LS1043ARDB Specification:
-------------------------
Memory subsystem:
 * 2GByte DDR4 SDRAM (32bit bus)
 * 128 Mbyte NOR flash single-chip memory
 * 512 Mbyte NAND flash
 * 16 Mbyte high-speed SPI flash
 * SD connector to interface with the SD memory card

Ethernet:
 * XFI 10G port
 * QSGMII with 4x 1G ports
 * Two RGMII ports

PCIe:
 * PCIe2 (Lanes C) to mini-PCIe slot
 * PCIe3 (Lanes D) to PCIe slot

USB 3.0: two super speed USB 3.0 type A ports

UART: supports two UARTs up to 115200 bps for console
