[LEDE-DEV] Files across reboot are not persisiting

[K.Mani]

    When we create a file on the booted board and reboot the file
doesn't persist.
    Environment:
    OpenWRT branch "Barrier Breaker" on Annapurna board, with
ALpine-v1(soc) is having NOR flash(MX25U25635F) 32MB

    I think mounting of rootfs_data type jffs2 is not happening in Preinit!
