[0/6] hw/i2c: Add NPCM7XX SMBus Device

Message

This patch set implements the System manager bus (SMBus) module in NPCM7XX
SoC. Basically, it emulates the data transactions of the module, not the
SDA/SCL levels. We have also added a QTest which contains read and write
operations for both single-byte and FIFO mode, and added basic I2C device
trees for npcm750-evb and quanta-gsj boards.

We also cleaned up the unimplemented GPIO devices in npcm7xx.c since they
are already implemented.
