i2c: Implement read function

Implement I2CDevice::read() by invoking i2c_smbus_read_xxx() APIs.
The code is referenced from i2c-tools' i2cget.c:

 https://github.com/ev3dev/i2c-tools/blob/ev3dev-stretch/tools/i2cget.c

Tested: Verify on Witherspoon that it reads the PSU ppgrade mode status
        register (1 byte) and CRC16 register (2 bytes) correctly.
