Add support for Solidrun's MX6 Cubox/Hummingboard.

For more information about these boards, please check:

U-Boot is capable of detecting the version of the board in run-time
and loads the correct dtb.

+To build a minimal support for these boards:
+
+    $ make mx6cubox_defconfig
+    $ make
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on an SD card:
+
+dd if=output/images/sdcard.img of=/dev/<your-microsd-device>
+
+For details about the medium image layout, see the definition in
+board/solidrun/mx6cubox/genimage.cfg.
