The tag is incorrect. The mentioned commit didn't add sm8150 bindings,
so it didn't have a bug.

Could you please extend the sm8250 case instead of defining a new one?
Also could you please check if there is a clock (like ahb_clk_src)
that uses bi_tcxo_ao instead of bi_tcxo? If so, we have to add this
clock to the bindings even if the driver doesn't use/model it at this
point.
