i2c lpcopen library can't address correctly 16 bit addresses on read command

[gustavosr8]

The 24xx64 eeprom driver uses two 8 bits field to address the i2c read command

openMMC/modules/eeprom_24xx64.c

Lines 40 to 60 in 3f659b9

	size_t eeprom_24xx64_read( uint8_t id, uint16_t address, uint8_t *rx_data, size_t buf_len, TickType_t timeout )
	{
	uint8_t i2c_addr;
	uint8_t i2c_interface;
	uint8_t rx_len = 0;
	uint8_t addr8[2];
	addr8[0] = (address >> 8) & 0xFF;
	addr8[1] = (address) & 0xFF;
	if ( rx_data == NULL ) {
	return 0;
	}
	if (i2c_take_by_chipid( id, &i2c_addr, &i2c_interface, timeout ) ) {
	rx_len = xI2CMasterWriteRead (i2c_interface, i2c_addr, addr8, rx_data, buf_len);
	i2c_give( i2c_interface );
	}
	return rx_len;
	}

but the lpcopen module that handle this expect only one 8 bit address

openMMC/port/ucontroller/nxp/lpc17xx/lpcopen/src/i2c_17xx_40xx.c

Lines 462 to 475 in 3b7ae35

	/* Transmit one byte and receive an array of bytes after a repeated start condition is generated in Master mode.
	* This function is useful for communicating with the I2C slave registers
	*/
	int Chip_I2C_MasterCmdRead(I2C_ID_T id, uint8_t slaveAddr, uint8_t cmd, uint8_t *buff, int len)
	{
	I2C_XFER_T xfer = {0};
	xfer.slaveAddr = slaveAddr;
	xfer.txBuff = &cmd;
	xfer.txSz = 1;
	xfer.rxBuff = buff;
	xfer.rxSz = len;
	while (Chip_I2C_MasterTransfer(id, &xfer) == I2C_STATUS_ARBLOST) {}
	return len - xfer.rxSz;
	}

For this reason, we need to build a custom function to handle this i2c transaction that accepts any size of command field.
