[media] cx18: Make RF analog TV work for newer HVR-1600 models with silicon tuners
A previous changes which added the newer model HVR-1600's and DTV support for
them, neglected to add RF analog TV for them. Fix RF analog TV for the newer
HVR-1600's which have a worldwide analog tuner assembly with a TDA18271 tuner
and TDA8295 demodulator.
Thanks go to Jeff Campbell and Mike Bradley for reproting the problem, and
also to Mike Bradley for doing a lot of the legwork to figure out the tuner
reset GPIO line, the demodulator I2C address, and that the GPIOs have to be
reinitialized after a cardtype switch.
