clk: handle CLK_OF_DECLARE in deep probe
An assigned-clock-parents referring to a fixed-clock will result in a warning: WARNING: clk: couldn't get parent clock 0 for /ethernet@fe300000 That's because the device for the fixed clock is created on demand and even after ensuring probe, no driver will have bound against it as CLK_OF_DECLARE operates outside the driver model. Fix this by creating devices and binding the dummy driver while iterating over the CLK_OF_DECLARE list. No functional change for systems not enabling deep-probe.
