Since pins and frequency are specific to module (pfla02), not base board
(pbab02), it is better to be initialized in corresponding dts file.
This patch fixes i2c2, i2c3 pin configuration which caused messages:
imx6q-pinctrl 20e0000.iomuxc: no groups defined in /soc/aips-bus at 02000000/iomuxc at 020e0000/i2c2grp
imx6q-pinctrl 20e0000.iomuxc: no groups defined in /soc/aips-bus at 02000000/iomuxc at 020e0000/i2c3grp
imx6q-pinctrl 20e0000.iomuxc: unable to find group for node i2c2grp
imx6q-pinctrl 20e0000.iomuxc: unable to find group for node i2c3grp
