The following changes were made, primarily to bring the cpci750 i2c driver in line with U-Boot's current I2C API: - Made i2c_init() globally accessible - Made i2c_read() and i2c_write() return an integer - Updated i2c_init() calls to pass in CONFIG_SYS_I2C_SLAVE in the offhand chance someone adds slave support in the future
