aspeed/i2c: introduce a state machine
The Aspeed I2C controller maintains a state machine in the command
register, which is mostly used for debug.
Let's start adding a few states to handle abnormal STOP
commands. Today, the model uses the busy status of the bus as a
condition to do so but it is not precise enough.
Also remove the ABNORMAL bit for failing TX commands. This is
incorrect with respect to the specs.
