Usually printing the SPL banner varies between architecture
or board codes.
- Some would print before relocation at the end board_init_f
  for making sure all initialization prior to this would happen
  properly. if at all there is a requirement for serial init,
  that happens properly since it prints all after that.
- Some would print after relocation at the spl_board_init for
  making sure all initialization prior to relocation would
  happen properly. Also debug uart on these cases would be
  available before relocation. So debug support is available
  in before and after relocation.

Rockchip SPL is following formar step to print the banner at
the end of board_init_f.

To support various custom use cases in SPL like leds, environment,
board detections later options like printing the banner after
relocation would be a better option. Printing banner would also
help to support debugging availability between relocation codes,
like debug uart available before relocation and banner availability
after relation.

By demonstrating all the above use cases, this patch is trying
to print the SPL banner after relocation.
