This patch adds a new defconfig for Cubieboard1 made by Cubietech. It is
based on the Allwinner A10 SoC. See:
http://www.cubietech.com/product-detail/cubieboard1.

The defconfig uses upstream U-Boot and Linux.

  - update kernel dts path (new vendor subdir)
  - update my email address in DEVELOPERS
  - add BR2_DOWNLOAD_FORCE_CHECK_HASHES=y to defconfig
  - add BR2_GLOBAL_PATCH_DIR and custom hashes (utils/add-custom-hashes)
  - minor improvements to readme.txt
  - add link to board details in commit message (requested by Giulio)
Changes v1 -> v2:
  - fix commit title
  - add entry to DEVELOPERS
