[U-Boot] [PATCH v1] tools/kwboot: Allow just -t to function

[Suriyan Ramasami]

When kwboot is invoked with -t <tty> the code implicitly assumes that one
of -b (boot message) or -d (debug message) with an image file is specified.
This is not necessarily true.

This allows kwboot -t <tty> to function.
