Add Arndale board support

The Arndale board is based on samsung's exynos5250 SOC. For spl generation, it depends on the patch at [5].

First patch provides the basic arndale board support. The second patch adds the MMC support.

Changes in v2:
- split from earlier patchset at [3] as per Minkyu
- Removed checkpatch errors pointed out by Wolfgang
- rebased to latest u-boot-samsung master branch
- created mmc_boot.c to remove dependency on consolidation patch at [4]
- split the mmc support to new patch as it depends on [2]

Dear Inderpal Singh,

This patch seems to conflict with Rajeshwari's patch.
http://patchwork.ozlabs.org/patch/256058/

So, this patch will be pending until merge.

Thanks,
Minkyu Kang.

This patch adds mmc support to the arndale board.
