Actually - that doesn't resolve the problem unless it all goes in via
the same tree still because the clock patch can only drop the #define if
the arch-vt8500 patch exists still - same as problem #2 I mentioned.

If the clock patch goes via Mikes tree he will need the arch-vt8500
patch as well - don't think it can be avoided.

Still easier to send the whole lot via arm-soc, then at least we can
resolve the patch conflicts without having to apply the patches twice.
