I forget what we had already discussed here. To clarify from my
side: it's ok to raise the limit if there are any known boards that
connect more than 8 8250 style uarts to external devices or
populated connectors.

On the other hand, I don't see any dts file at the moment that
has more than the maximum of 8 in k3-am642-tqma64xxl-mbax4xxl.dts.

If you are adding another board that has more, it helps to
clarify in the patch description that this is indeed a board
requirement, and not just done because the chip has additional
unused uarts.
