ppc4xx: Handle i2c stuck on combined xfer ppc4xx i2c master gets stuck on errors while repeated start is active. Can be easily reproduced by "i2c md" on an unpopulated i2c address. There is not stop condition given, scl remains pulled low. The only way out seems to be doing a stop manually and then a soft reset.
