ppc4xx_i2c: Rewrite to model hardware more closely
Rewrite to make it closer to how real device works so that guest OS
drivers can access I2C devices. Previously this was only a hack to
allow U-Boot to get past accessing SPD EEPROMs but to support other
I2C devices and allow guests to access them we need to model real
device more properly.
