As Mainlining effort for SolidRun CuBox has been carried out on the
Engineering Sample, the board DTS was reflecting this. Actually,
SolidRun CuBox comes in three different variants: Engineering Sample (ES),
production with 1GB RAM (1G), and production with 2GB RAM (2G).
Therefore, we split the current dove-cubox.dts into a common board include
and one board dts for each of the above variants.

Do you anticipate any other differences between the 1G and the 2G?
Otherwise, I'm inclined to just have a "solidrun,cubox". The bootloader
should be setting the amount of RAM at boottime anyway.
No, there is no known difference between 1G and 2G except doubled RAM.
I'll squash the two back into a single non-ES dts.
About the board specific compatibles, I am not so sure if we should
keep them at all. "solidrun,cubox" for all three variants should be
enough. checkpatch is already choking on every unknown compatible it
sees and documenting each individual board clearly doesn't scale well.

Hmm, I guess those who have it know about ES=="Engineering Sample" but
as I have to do a v2 anyway, I'll fix it up.
Thanks!
