ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02 

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@02000000/iomuxc@020e0000/i2c2grp
