imx: ventana: re-enable late board info display

3b1f6811 caused a regression that removes
board info dispaly for Gateworks Ventana boards because it made the invalid
assumption that CONFIG_DISPLAY_BOARDINFO_LATE was the same thing as
CONFIG_DISPLAY_BOARDINFO.

Ventana needs to call show_board_info in late init because we need to have
the i2c eeprom based model info. Re-define CONFIG_DISPLAY_BOARDINFO_LATE
to allow that to happen.
