AF9015 firmware does not like if it gets interrupted by I2C adapter request on some critical phases. During normal operation I2C adapter is used only 2nd demodulator and tuner on dual tuner devices. Override demodulator callbacks and use mutex for limit access to those "critical" paths to keep AF9015 happy.
