mxs: i2c: Implement algorithm to set up arbitrary i2c speed
This algorithm computes the values of TIMING{0,1,2} registers for the MX28 I2C block. This algorithm was derived by using a scope, but the result seems correct. The resulting values programmed into the registers do not correlate with the contents in datasheet. When using the values from the datasheet, the I2C clock were completely wrong.
