V4L/DVB (6447): tuner: add i2c_gate_ctrl function to struct analog_tuner_ops
In some designs, the tuner silicon may be on an i2c bus behind an i2c gate,
controlled by the analog demodulator. 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.
