[meta-freescale] Incorrect GPIO value with Kernel 3.14.28

[Yannick Calmettes]

You can see below all the things I do related to this GPIO.
In 3.10.53 it returns "1".

*In DTS :*
MX6QDL_PAD_SD4_DAT1__GPIO2_IO09 0xC0000000

*At startup :*
echo 41 > /sys/class/gpio/export
echo "in" > /sys/class/gpio/gpio41/direction

*On Terminal :*
root at mx6dl-rev0-main:~# cat /sys/class/gpio/gpio41/value
512
