[CMD][SECO_CONFIG] fix fdt list variables overwrite error
After running seco_config fdtoverlay, file list variables such as
fdt_overlay_video_list were being overwritten with their tokenization,
so only the first item was being left.
This was then passed to seco_fdt_overlay apply_all and so was the
only overlay applied.
Make sure to leave the original string as is.
