ARM: socfpga: Add support for DENX MCV SoM and MCVEVK baseboard

Add support for the DENX MCV SoM and MCVEVK baseboard. The SoM contains
eMMC, DRAM, Altera Cyclone V SoC. The baseboard contains CAN ports, UART
ports, STMPE811 touchscreen controller, USB OTG port, ethernet port and
a lot of IO pins.
