arm: socfpga: Re-add support for Aries MCV SoM and MCVEV[KP] board

Re-add support for Aries Embedded MCV SoM, which is CycloneV based
and the associated MCVEVK and MCVEVP baseboard. The board can boot
from eMMC. Ethernet and USB is supported.

The Aries Embedded boards have been removed with commit 03b54997d568
("board/aries: Remove"). I will now take care of them.

The device-tree files are from mainline Linux commit e93c9c99a629
("Linux v5.1)".
