No, this is totally pointless. Simply establish a clk lookup for the
configuration you are running on in your board code and always have
clk_get() operate on a fixed id. You can use this same scheme with any
optional clocks you have too, and reconfigure according to whether the
lookups for optional clocks succeeded or not.
