Add an I2C bus driver for virtio para-virtualization. The controller can be emulated by the backend driver in any device model software by following the virtio protocol. This driver communicates with the backend driver through a virtio I2C message structure which includes following parts: - Header: i2c_msg addr, flags, len. - Data buffer: the pointer to the I2C msg data. - Status: the
