V4L/DVB (9203): ks0127: convert i2c driver for new i2c API 

- Convert to use v4l2-i2c-drv-legacy.h to be able to handle the new i2c API
- Cleanups
- Use v4l_dbg/v4l_info to have uniform kernel messages

* An explanation from kayork@mail.utexas.edu:
*
* During I2C reads, the KS0127 only samples for a stop condition
* during the place where the acknoledge bit should be. Any standard
* during the place where the acknowledge bit should be. Any standard
* I2C implementation (correctly) throws in another clock transition
* at the 9th bit, and the KS0127 will not recognize the stop condition
* and will continue to clock out data.
*
* So we have to do the read ourself. Big deal.
