We already have a method to control such i2c gates when they are controlled by the digital demodulator, but in some hybrid designs, there may be an i2c gate controlled by each demodulator. For example, when in analog tuning mode, one would access the tuner by opening the i2c gate controlled by the analog demodulator, while when in digital tuning mode, one would access the tuner by opening the i2c gate controlled by the digital demodulator. We must add this callback function to analog_tuner_ops in order to handle such configurations.
