If the UART has no FIFO (in the 16550-sense), then sc_txfifosz

But where is this set? The ns8250_bus_probe() function returns
early when it
detects a FIFO-less device, leaving sc_txfifosz at its pre-
initialized value
(i.e. zero). And it doesn't seem to get set anywhere else, either.
Uhm, on line 817 in uart_dev_ns8250.c, which falls in function
uart_bus_probe(), both the rx and tx fifo sizes are set to 1.
This is for the case there's no fifo.
