This patchset adds support for automatic selection of the best parent

to that requested. It can be disabled by a new CLK_SET_RATE_NO_REPARENT
flag (which is set for all uses of clk_register_mux().

This works by way of adding a new op, determine_rate, similar to
round_rate but with an extra parameter to allow the clock driver to
optionally select a different parent clock. This is used in
clk_calc_new_rates to decide whether to initiate a set_parent operation.

I'd like to see this go into 3.11. We can tackle the larger problem that
Saravana brought up later on since we're no worse off than we already
are without these patches.

Feel free to add my reviewed-by to all patches.
