This commit implements the single-byte mode of the SMBus. Each Nuvoton SoC has 16 System Management Bus (SMBus). These buses compliant with SMBus and I2C protocol. This patch implements the single-byte mode of the SMBus. In this mode, the user sends or receives a byte each time. The SMBus device transmits it to the underlying i2c device and sends an interrupt back to the QEMU guest.
