MLK-12573 ARM: dts: set LCD_nPWREN low to make VLCD_3V3 output 3V3.
Q901 (IRLML6401) is p-channel MOSET, need set pin1 (LCD_nPWREN) to low
to let pin3 output be 3V3. Normally when pin1 is high, then pin3
output should be gated. It was working previously due to some leakage.
Correct the enable logic from the software viewpoint.
