tiny-printf: endless loop for %llu format

[Matwey V. Kornilov]

Hi,

I am trying to boot AM335x platform via TFTP and found another one
issue related to tiny-printf:

print_size() in  lib/display_options.c  relies on

    printf("%llu Bytes%s", size, s);

and it surprisingly leads to infinite looping when tiny-printf is used in SPL.
So, I am afraid that TFTP in SPL is currently broken for every board.
