I think this would be easier to follow if it were split in half:
the first half migrating mt8365_simple_gate to mtk_gate, and the
second half converting to mtk_clk_simple_probe.

I assume git would generate better diffs after that.

This would get split in half as well. The macro cleanups go with the
first half, and the switch to module_platform_driver goes with the
second.

This should be in the previous patch?

Could you also remove some of the other inclusions that don't get
referenced after this patch?

Misc. unmentioned change. It makes sense, but please mention it.
