Initial DT clock bindings

[Grant Likely]

Hi everyone,

Here's my second posting of initial device tree bindings for clocks.  I'm
a lot happier with how this is looking now, and Versatile is pretty much
entirely converted.  In fact, the realview, integrator and vexpress platforms
are pretty close now too.  Just for fun I went and converted Highbank also.

There is still stuff to clean up, and I want to add test cases for the new
clock framework, but otherwise I think it is pretty complete.  There are
some changes to the binding documentation that you'll want to pay attention
to.

This series is based on v3.2-rc5 plus the of_parse_phandle_args() patches
that I posted a couple of hours ago.
