[PATCH] LifeView FlyTV Platinum FM: GPIO usage



This is take two of a patch that should have appeared two days ago, before
yesterday's "remote control" patch for the same card.

This patch sets unconnected GPIO to Output to keep them from floating (just
good driver writing practice, being nice to the chip), and uses GPIO16 to
switch TV vs.  FM - this pin switches inputs onto the tuner, as well as the
audio output from the tuner into the 7135 SIF input.  Consequently, FM
radio support is being un-commented because it's now working (sort of, see
below).

These two patches get the card almost fully operational; there appears to
be a bug in tda8290.c remaining that puts an offset onto the tuned
frequency in FM radio mode.  We're investigating.
