I think that option is pretty much redundant. This is x86. There is no
device tree to enable devices.
There are only two possible scenarios: use ns16550 or not. Building the
driver and maybe use it does not exist. And we can use
CONFIG_DRIVER_SERIAL_NS16550 to choose.
Somewhat unrelated: I think this driver should be avoided if possible. I'm
quite certain, that the original use-case for this was a bug in barebox and
not a broken EFI serial driver.
