The platform device is required for the deferred probe that can happen if the
DFLL driver hasn't initialized yet, and module_init() callbacks don't seem to
respect -EPROBE_DEFER.

Oh, which call in this file will return EPROBE_DEFER? I couldn't make out
which one will depend on DFLL driver.

It's this:

+static int tegra124_cpufreq_probe(struct platform_device *pdev)
+{
[...]
+
+	dfll_clk = of_clk_get_by_name(cpu_dev->of_node, "dfll");
+	if (IS_ERR(dfll_clk)) {
+		ret = PTR_ERR(dfll_clk);
+		goto out_put_cpu_clk;
+	}
