i2c: Implement write function

Implement I2CDevice::write() by invoking i2c_smbus_write_xxx() APIs.
The code is referenced from i2c-tools' i2cset.c:

 https://github.com/ev3dev/i2c-tools/blob/ev3dev-stretch/tools/i2cset.c

Tested: Verify on Witherspoon that it writes the PSU unlock upgrade
        command and boot flag successfully.
