New I2C framework, introduced after v2013.07 final release, imposed I2C code adjustment for some Samsung boards - namely Trats, GONI and Universal_c210. Those boards were using schematic based I2C enumeration (I2C_5, I2C_9). However, new I2C framework imposes usage of logical I2C adapters numbering (e.g. I2C_0, I2C_1, etc). Additionally, I2C_GET_* macros were replaced with i2c_*_bus_num() functions. Trats board gained definition of second soft I2C adapter.
