V4L/DVB (5899): bttv: Fix Viewcast Osprey 440 support
Various gpio and mux settings for the Osprey 440 weren't correct. Fix them and provide some documentation about how the gpios work. The osprey eeprom routine wasn't run for the 440, add it. It was also crap, re-written to be better. Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample rate is fixed at 32kHz, as the driver doesn't support different rates for digital input mode, though the card can select the rate from 32, 44.1, or 48 kHz via gpio. Setting the audio gain via ALSA isn't supported yet; a userspace tool that programs the X9221 via i2c-dev must be used. The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC used, resulting in extremely garbled sound. That is fixed in a followup patch.
