Pulled into arm/drivers for now.

I have drafted a related patch recently, regarding the related
arch/arm/plat-samsung/cpu.c file. This is part of a longer series
I'm working on, see https://pastebin.com/ZqeU3Mth for the
current version of this patch. The observation is that mach-exynos
is almost completely independent of plat-samsung these days, and my
patch removes the last obstacle from separating the two. I have
another set of patches to do the same for mach-s5pv210 (which shares
half of its pm.c with plat-samsung, but nothing else).
