commit 7f59b319111bbc3a5f32730c8a43b201e9522f52 upstream.

GPIO4_11 is on pin 152(MX6DL_PAD_KEY_ROW2) and not on pin 151(MX6DL_PAD_KEY_ROW1).

I found the error while booting a mainline kernel on APF6S SoM and noticed the following message:

[    2.609337] imx6dl-pinctrl 20e0000.iomuxc: pin MX6DL_PAD_KEY_ROW1
already requested by 20a8000.gpio:105; cannot claim for 20a8000.gpio:107
[    2.621884] imx6dl-pinctrl 20e0000.iomuxc: pin-151 (20a8000.gpio:107)
status -22
[    2.629303] spi_imx 2008000.ecspi: Can't get CS GPIO 107

With this patch, the message is gone and spi_imx driver probes correctly.

Fixes bb728d662bed ("ARM: dts: add gpio-ranges property to iMX GPIO controllers")
