These should all be:

I don't think you need base for any of these.
mtk_clk_register_gates() will use syscon_node_to_regmap() to lookup
the regmap by itself.

Unrelated to this patch, but:
I think each clock node should statically declare its
clk_onecell_data, and pass it to mtk_alloc_clk_data().
mtk_alloc_clk_data() should then just allocate and initialize the clks array.
