FYI: even if a booloader enablesq clocks, it's important that the kernel
enable clocks that it uses so the kernel can be independent of any

The master branch in my tree just tracks mainline master branch.

To avoid conflicts with other on-going DT changes, the DT patches should
probably be based on top of my v4.12/dt64 branch.
