[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.
