[GIT PULL 0/2] Samsung pull-request for v3.12

Hi Arnd and Olof,

Here is Samsung cleanup and Exynos DT stuff for v3.12.

They include non-dt cleanup and unused codes, and add exynos4412-trats2
board and update Arndale board, exynos5420 and exynos4 series.

Just note, I'm holding on defconfig update branch because of concern for
exynos5440_defconfig and I'm waiting for Mike's clk update for s3c64xx
common clk and addressing comments for several DT patches.

If any problems, please let me know.

Thanks,
Kukjin
