Same problem on an IB8000 Atom Braswell board using 16.04. Also shows the two ports when checking with acpidump, but the bionic OEM kernel mentioned here did not fix it when installed on my 16.04. It booted fine but no ttyS or ttyHS... What really did the trick was the Debian 4.16.0-2 mentioned above as well. This one brought back the ports on the normal ttyS names on 16.04!
