Prevent dt_driver_device_from_node_idx_prop() to request driver probe
deferral when needing to skip phandle arguments cells related to
providers not yet registered. When skipping these phandle argument cells
we don't really need the skipped provider is registered, we can read
the #xxx-cells property in the provider DT node straight.
For example, consider a driver which DT node defines:
clocks = <&foo_clock 1 2 3>, <&bar_clock 2>;
clock-names = "foo", "bar";
If driver calls clk_get_by_name(fdt, node, "bar"), it does not need to
wait &foo_clock related driver to be already probed, it does not even
need the driver to be ever probed.
