i2c: add i2c_core and prepare for new multibus support
This Patch introduce the new i2c_core file, which holds the I2C core functions, for the rework of the multibus/ multiadapter support. Also adds changes in i2c.h for the new I2C multibus/multiadapter support. This new support can be activated with the CONFIG_SYS_I2C define.
