There are no more non-common calls in clk_mt7986_topckgen_probe():
migrate this driver to mtk_clk_simple_probe().

Thanks for doing this! I read the patch 23 first and I thought the
mtk_clk_simple_probe() cannot be used like that. So I got the whole series
and found this patch to extend mtk_clk_simple_probe. Cool.

Replying for the wrong patch - this message should go to patch 12.
