clock-output-names is now required for most of sunxi clock nodes, to
provide the name of the corresponding clock. Add the new requirements,
exceptions, as well as examples.

As we discussed on IRC, I wonder if such verbosity is actually needed.
Maybe we should dictate that all clocks must list their corresponding
outputs on clock-output-names (with it being the module name if it only
has one output).
