Remove old i2c driver remains 

This i2c.* files were just holding some helper functions, like a I2CInit
wrapper and GA discovery.
Just move these function to their right places

/*! @brief Reads own I2C slave address using GA pins

* Based on coreipm/coreipm/mmc.c

* Reads the GA pins, performing an unconnection checking, to define the device I2C slave address, as specified by MicroTCA documentation.
*
* @return 7-bit Slave Address
*
* @todo Develop a function to discover the Geographic Address once (checking the GA pins)
* and store it into a global variable, since everytime a IPMI message is built
* (request or response) the MMC has to check its own address to fill the rs/rqSA field,
* and it takes some time to go through all this function.
