[PATCH qemu 3/3] ast2400: add a temp sensor device on I2C bus 3

[Cédric Le Goater]

The palmetto platform has a tmp421 device. Qemu has not (yet). Let's
use a tmp105 instead.

The aspeed-bmc-opp-palmetto dts file should to be changed consequently
with :

	i2c2: i2c-bus at c0 {
		tmp423 at 4c {
			compatible = "ti,tmp105";
			reg = <0x4c>;
		};
	};

Temperature can be changed from the monitor with :

	(qemu) qom-set /machine/unattached/device[2] temperature 12000
