I don't see any reason why we need this patch though. The binding
works as is, so supporting different styles doesn't seem like a
good idea to me. Let's just keep what we have? Even if a sub-node
like cpu or codec gets more than one element in the clocks list
property, we can make that work by passing a clock-name then
based on some sort of other knowledge.
