NS16550: buffer reads
This improves the performance of U-Boot when accepting rapid input,
such as pasting a sequence of commands.
Without this patch, on P4080DS I see a maximum of around 5 mw.l lines can
be pasted. With this patch, it handles around 70 lines before lossage,
long enough for most things you'd paste.
