i2c: mxs: Fix TIMING2 register value
According to FSL, the value in the TIMING2 register shall be 0x00300030 instead of what's written in the datasheet. This new value correlates with older STMP36xx datasheet. Issues were detected in Linux when this register was misconfigured, so write this correct value.
