MLK-12551: imx6ul evk: fix 74LV OE usage
Fix 74LV OE gpio index. pinmux is correct, but gpio index
is wrong, so gpio output will not have effect, since we
use wrong GPIO5_IO18, but not correct GPIO5_IO8.
And at the end of the initialization of 74lv init, should
keep OE voltage level at LOW, but not high.
