soc/cores/i2c: rewrite state machine
...
* Fix READ: was reading too many bits
* CLeaner transitions between states: ACK=>IDLE with scl=0. Other to IDLE with scl=1
* Now cleanly supports RESTART
* conceptual support for compound commands - not exposed yet
* fix tests: now appears to be I2C compliant

* refactor to eliminate some copy/paste
