Sigh. I'd like to just drop the Exynos MCT patches, but they're now a bit down
into the next/drivers branch with various dependencies into later branches too.

Given that things are already broken, I'll just fix this up in an incremental
patch on top of the late/clksrc branch for now.

Agreed. Hopefully we can remove the non-DT code when Exynos is going DT-only.
