configs: colibri-imx7: Fix bad block table in flash configuration

Make sure that the bad block table in flash is used on Colibri iMX7.
Without this configuration enabled U-Boot corrupts the bad block table
and Linux will update the table on each reboot. The corruption occurs
because if CONFIG_SYS_NAND_USE_FLASH_BBT is not set, U-boot will store
bad blocks out of band, while the Linux driver for the iMX7 will store
them in band in a bad block table.
