Yeah, that was a bit hacky, but I didn't see a better solution with the MSTP
driver. CPG/MSSR would solve that differently.

I'm wondering whether we should keep this one for now?
Dropping it changes the clock name from "zb_clk" to "zb".

Nothing should rely on that, though, but keeping "zb" would allow us to e.g.
change the MSTP driver to match on clock name instead of node name, and drop
clock-output-names and rename the clock node later.
