imx6ulevk: fix 74LV OE usage

Browse source 
Fix 74LV OE gpio index. 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 to make 74lv output the correct
voltage.
