clk: introduce clk_dev_binded

clk: introduce clk_dev_binded

When support Clock Common Framework, U-Boot use dev for
clk tree information, there is no clk->parent. When
support composite clk, it contains mux/gate/divider,
but the mux/gate/divider is not binded with device.
So we could not use dev_get_uclass_priv to get the correct
clk_mux/gate/divider. So add clk_dev_binded to let
choose the correct method.
