    ath79: mikrotik: set compat version for NAND devices
    
    Currently, trying to upgrade on a MikroTik NAND device will force you to
    use sysupgrade -n due to:
    upgrade: The device is supported, but the config is incompatible to the new image (1.0->1.1). Please upgrade without keeping config (sysupgrade -n).
    upgrade: NAND images switched to yafut. If running older image, reinstall from initramfs.
    
    So instead of having users manually set the new compat version lets do
    what other targets do and set it for all NAND devices after good boot.
