Currently it is possible to call "kwboot -b -t /dev/ttyUSB0" but not to
call "kwboot -b /dev/ttyUSB0".
Fix it by not trying to process the last argv[], which is non-getopt()
option (tty path) as the image path for -b.
Fixes: c513fe47dca2 ("tools: kwboot: Allow to use option -b without image path")

Please correct me if I am wrong but AFAIU, this change makes it possible
to use kwboot to also boot images on some of the Armada 64 bit
platforms, as commented and tested by Marcel.
If this is the case, could you please update the documentation or at
least add a note with some comments to the commit text?
Thanks,
Stefan
