[PATCH v3 0/5] hw/i2c: Add NPCM7XX SMBus Device

[Hao Wu]

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 devices
for npcm750-evb and quanta-gsj boards.

Changes since v2:
- Remove first patch (GPIO) since it's already applied to target-arm.next
- Rename NPCM7XX_SMBUS_FIFO_EN to NPCM7XX_SMBUS_VERSION_FIFO_SUPPORTED
  to indicate it's a register field of the VERSION reg.
- Add select AT24C in hw/arm/Kconfig.
- Minor additional commit messages and comments to clarify things.

Changes since v1:
- Fix errors for i2c device addresses for temperature sensors in GSJ machine
- Use at24c device to emulate GSJ EEPROM. It supports more than 256 bytes.
- Fill in VMState in npcm7xx_smbus.c
- Change commit message in patch 3 and 4
- Fix order in npcm7xx.c IRQ list
- Add a few extra comments to make things clearer
