i2c:samsung: Adjust Trats, GONI and Universal_c210 boards to work with new I2C framework

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.
