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]

Changes in v5:
- Fix comments suggested by Minkyu
- Added SPDX-License-Identifier to new files

Changes in v6:
- Fixed missed out sorting of Maintainers entry
Changes in v7:
- Fixed regression caused due to v6.
- rebased to latest u-boot-samsung master branch
- Fixed checkpatch warning for parenthesis alignment.
