[PATCH v2 2/2] ARM: dts: mvebu: split SolidRun CuBox into variants

[Sebastian Hesselbarth]

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 base current dove-cubox.dts on to the 1G production
variant and add a ES dts to add required quirk for misrouted SDHCI
card detect on top of dove-cubox.dts. For the 2G variant we rely on
the bootloader to setup correct RAM size.

Changelog:
v1->v2:
- drop 2G board dts and rely on bootloader (Suggested by Jason Cooper)
- rework board files to allow to include 1G into ES and add quirks only
