ipmi: ipmb: Fix build error while CONFIG_I2C is set to m

If CONFIG_I2C is m and CONFIG_I2C_SLAVE is y,
building with CONFIG_IPMB_DEVICE_INTERFACE setting to
y will fail:

drivers/char/ipmi/ipmb_dev_int.o: In function `ipmb_remove':
ipmb_dev_int.c: undefined reference to `i2c_slave_unregister'
drivers/char/ipmi/ipmb_dev_int.o: In function `ipmb_write':
ipmb_dev_int.c: undefined reference to `i2c_smbus_write_block_data'
drivers/char/ipmi/ipmb_dev_int.o: In function `ipmb_probe':
ipmb_dev_int.c: undefined reference to `i2c_slave_register'
drivers/char/ipmi/ipmb_dev_int.o: In function `ipmb_driver_init':
ipmb_dev_int.c: undefined reference to `i2c_register_driver'
drivers/char/ipmi/ipmb_dev_int.o: In function `ipmb_driver_exit':
ipmb_dev_int.c: undefined reference to `i2c_del_driver'

Add I2C Kconfig dependency to fix this.
