[U-Boot] Different Port for TFTP communication

As is, this cannot be changed.  The TFTP port number is hard wired
in the code - see "net/tftp.c":

...
 18 /* Well known TFTP port # */
 19 #define WELL_KNOWN_PORT 69
...

Of course it should be trivial to add a config option for this, or
even make it changable at runtime.  But I have to admit that I don't
see many actual use cases for such a modification.

Could you please explain why you need to do this - is this just some
exotic environment, or is this needed for some more general use case?

Best regards,

Wolfgang Denk
