From: Jonathan Humphreys j-humphreys@ti.com
For use-cases such as USB DFU Boot, "spl_dfu_cmd()" will setup the appropriate value for "dfu_alt_info". To facilitate such use-cases and in order to avoid overwriting the value of "dfu_alt_info", invoke the "set_dfu_alt_info()" function only when "dfu_alt_info" is not defined.
