The Sony BTF PG472Z has an internal MPX to deal with mono/stereo/bilingual
audio. This is split off from the wis-sony-tuner driver that is part of
the go7007 driver as it should be a separate i2c sub-device driver.
The wis-sony-tuner is really three i2c devices: a standard tuner, a tda9887
compatible demodulator and this mpx. After this patch the wis-sony-tuner
can be replaced by this driver and the standard tuner driver.
