ARM: dts: imx6qdl-nitrogen6x: remove duplicate iomux entry
The NANDF_CS2 pad is also part of the wlan-vmmcgrp iomux group.
Removing is from the usdhc2grp group avoids the following error:
imx6q-pinctrl
20e0000.iomuxc: pin MX6Q_PAD_NANDF_CS2 already requested
by regulators:regulator@4; cannot claim for

20e0000.iomuxc: pin-187 (
2194000.usdhc) status -22
imx6q-pinctrl
20e0000.iomuxc: could not request pin 187
(MX6Q_PAD_NANDF_CS2) from group usdhc2grp on device
