[PATCH v2] ARM: dts: imx6ull: fix ubi filesystem mount failed

[dillon.minfei at gmail.com]

From: dillon min <dillon.minfei at gmail.com>

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
