iio: gyro: mpu3050: add I2C dependency

The new mpu3050 driver fails to build if I2C is disabled:

drivers/iio/built-in.o: In function `mpu3050_i2c_driver_exit':
mpu3050-i2c.c:(.exit.text+0x17f): undefined reference to `i2c_del_driver'
drivers/iio/built-in.o: In function `mpu3050_i2c_driver_init':
mpu3050-i2c.c:(.init.text+0x215): undefined reference to `i2c_register_driver'

This adds a Kconfig dependency to ensure we only build it when I2C
is available.
