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.
