Most of the smdkv310 features are common with other exynos4 boards. To permit easier addition of driver model support, use the common file and add a device tree file.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v4: - Rebase on top of master (CONFIG_OF settings moved to Kconfig)
Changes in v3: None Changes in v2: - Leave in a few configs which are not in fact common to all boards
