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

["Thomas Dörfler" <Thomas.Doerfler@embedded-brains.de>]

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.
