I don't think changing this is right. First, 'ns16550' is what's
documented in the DT spec (and ePAPR which it's based on).

Second, these dts files are pretty mature/stable, so I'm less inclined
to change them. AFAICT, this change either enables the fifo (which
would be an untested change in behavior) or has no effect because the
fifo is auto-detected.

Well, that's annoying...
