clk: ignore of_device_ensure_probed error in clock lookup
For CLK_OF_DECLARE clocks there is no driver that is bound to the device, so the lookup fails before even trying to find the provider, breaking the parent_ready() logic used when initializing the declared providers. Ignore the return code from of_device_ensure_probed to allow the lookup to proceed as usual. If of_device_ensure_probed the lookup will also fail, as no provider will be found.
