    ARM: dts: imx6ull: fix ubi filesystem mount failed
    
    [ Upstream commit e4817a1b6b77db538bc0141c3b138f2df803ce87 ]
    
    For NAND Ecc layout, there is a dependency from old kernel's nand driver
    setting and current. if old kernel use 4 bit ecc , we should use 4 bit
    in new kernel either. else will run into following error at filesystem
    mounting.
    
    So, enable fsl,use-minimum-ecc from device tree, to fix this mismatch
