I think you are trying to follow previous s4 scheme - to introduce a new
compatible string, while I think it's not necessary or even wrong, this will just
make the dt_match_list longer but without obvious benefits..

as Conor already raised this question in previous dt-binding patch[4/6],
how about just using 'amlogic,meson-g12a-uart' which is the first compatible
introduced.

if people agree, we could also drop 'amlogic,meson-s4-uart' since it use same
compatible data as gl12a, anyway it should be separated into another patch..
