Since commit 9484f2cb8332 ("clk: samsung: exynos-clkout: convert to
module driver") this driver is instantiated as MFD-cell (matched by
platform device name) not as a real platform device created by OF code.
Remove of_match_table and change related MODULE_DEVICE_TABLE to simple
MODULE_ALIAS to avoid further confusion.

As mentioned by Krzysztof in v1, please create a `platform_device_id` table so
that this is scalable in case we need to add other aliases in the future. For
example, something like this:
static const struct platform_device_id exynos_clkout_platform_ids[] = {
{ "exynos-clkout" },
{}
};
MODULE_DEVICE_TABLE(platform, exynos_clkout_platform_ids);
static struct platform_driver exynos_clkout_driver = {
.driver = {
.name = "exynos-clkout",
.pm = &exynos_clkout_pm_ops,
},
.probe = exynos_clkout_probe,
.id_table = exynos_clkout_platform_ids,
...
Thanks,
Will
