au8522: make use of hybrid framework so analog/digital demod can share state

From: Devin Heitmueller <dheitmueller@linuxtv.org>

Make use of the hybrid tuner framework so the analog and digital parts of the
au8522 demodulator can make use of the same shared state.

Thanks to Michael Krufky <mkrufky@linuxtv.org> and Steven Toth
<stoth@linuxtv.org> for providing sample hardware, engineering level support,
and testing.
