hw/i2c: Implement NPCM7XX SMBus Module Single Mode
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.
