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. Signed-off-by: Peng Fan <peng.fan@nxp.com>
