Err, no you haven't, not with that grep.  What you've found are the places
which enable this, and say "yes, I have clk_prepare".

What HAVE_CLK_PREPARE is about though is providing a transition path between
drivers using clk_prepare() to platforms which _don't_ have a clk_prepare()
implementation - and when it's unset, it provides a default implementation.

So, finding all those places where the symbol exists is the exact opposite
of what you need to be doing.  You need to find those platforms which have
CLK support, but which don't have HAVE_CLK_PREPARE selected.
