V4L/DVB (3112): Several fixes for Hauppauge Roselyn Design (blackbird)

- This patch adds eeprom awareness for the Roslyn. In effect, the
blackbird will query the tuner V4L2_STD_xxxx definitions to determine
whether it's connected to a NTSC or PAL tuner. Based on that, various
default values will change for blackbird encoding.
- Fixes back panel SVIDEO/COMPOSITE with audio, work properly.
- Fixes a problem with lip sync issues, due to bad framerate vs
audio rate assumptions.
- Fixed a problem with the GPIO configuration in cx88-cards.
- Removed the comments in cx88-cards that made no sense.
