I'm assuming that clk_put will be specific to the implementation; fixed clocks 
probably won't need to do anything, but others may need a refcount, etc.

We don't have a struct clk to use clk_get on, so it remains a non-clock-
specific function.

We'll probably need the symmetry for some cases though, I think that a 
__clk_get(struct clk *) member of clk_operations would work for this, to be 
called by clk_get.

Cheers,


Jeremy
