It seems patches from Tomasz [1] will likely make it to 3.10, thus
it is fine to apply Kukjin's patch as far as we are concerned.

Besides, it seems some drivers are already broken with ATAGS booting
(e.g. Exynos DRM, SDHCI) due to introduction of the common clock
framework driver. It doesn't seem worthwhile to spend time fixing
this, I would rather focus on improving the DT support.

Sorry for any confusion.
