I have seen boards use the GPIO_3/6 pads instead of EIM_D17/D18 for
I2C3, but the EIM_D17/D18 are indeed documented as "I2C1" pins at the
pfla02 connector level.

Yes, that is why I thought about moving it into pfla02. But apart from
it, i2c2grp i2c3grp nodes was wrongly placed under iomuxc node while
it should be grouped inside of it, like in imx6q-phytec-pfla02 to
which it was moved with this patch.
Because of this specified i2c wasn't working correctly and caused
messages:
imx6q-pinctrl 20e0000.iomuxc: no groups defined in
/soc/aips-bus@02000000/iomuxc@020e0000/i2c2grp
imx6q-pinctrl 20e0000.iomuxc: no groups defined in
/soc/aips-bus@02000000/iomuxc@020e0000/i2c3grp
imx6q-pinctrl 20e0000.iomuxc: unable to find group for node i2c2grp
imx6q-pinctrl 20e0000.iomuxc: unable to find group for node i2c3grp
Added this into commit message with new patchset.
Best regards,
Lavnikevich Dmitry
