Note that this series also changes the way clocks are organized. We have
many clocks on i.MX which implemenent set_parent and set_rate at
once. Now with the split into building blocks only the multiplexers
implement set_parent. It's no longer possible in general to call
set_parent on clocks given to drivers as these are mostly dividers and
gates which do not allow to change its parent.

The upside of this change is that it's really simple and straight
forward to implement a clock tree which can be easily reviewed with
the datasheet.

There will be updates to this series as I found some leftovers from
earlier versions of this series.
