[U-Boot] [Patch] bootelf should allow arguments passing to called program

The bootelf command is written to pass the command line arguments to the
called program, but the command list entry limits the number of
arguments to 2 (including the command itself and the image address).

Changing the command list entry allows passing command line arguments to
the called program.
