    mediatek: mt7622: fix rootfs/ubi detection for Xiaomi AX6S
    
    By specifying the flag "denx,fit" for partition "kernel", the kernel
    try to find rootfs in the same partition during boot. Reality is that
    the placement of rootfs is precisely determined by the name of another
    partition -"ubi".
    It was also found that on some device (for example devices with NAND
    chips), the "Denx search engine" manages to find roots at the end of
    partition "kernel", but such partition doesn't exist and is empty
    there.
    
    Fix this by removing the "denx,fit" flag from partition "kernel". With
    this change the original behavior of searchif rootfs in partition "ubi"
    is restored.
