i2c: mxs: Set I2C timing registers for mxs-i2c
This patch configures the I2C bus timing registers according to information passed via DT. Currently, 100kHz and 400kHz modes are supported. The TIMING2 register value is wrong in the documentation for i.MX28! This was found and fixed by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Marek Vasut <marex@denx.de> Signed-off-by: Wolfram Sang <w.sang@pengutronix.de>
