[PATCH 1/8] i2c: rename core source file to allow refactorization

[Wolfram Sang]

The I2C core became quite huge and its monolithic structure makes
maintenance hard. So, prepare to break out some functionality into
seperate files by renaming the source file. Note that we keep the
resulting object name constant to avoid regressions.
