Large EEPROMs, e.g. 24lc32, need 2 byte to address the internal memory. These devices require that the high byte of the internal address has to be written first. The mxs_i2c driver currently writes the address' low byte first.

The following patch fixes the byte order of the internal address that should be written to the I2C device.
