[PATCH] V4L: Miscellaneous fixes

- Fixed some bttv card numbers.

- BTTV and SAA7134 version numbers incremented to reflect changes.

- pci_dma_supported() is called after pci_set_dma_mask() which
  already did check that for us. This patch removes the unneeded call to
  pci_dma_supported() at bttv-driver.c

- Ensure a sufficient I2C bus idle time between 2 messages for
  saa7134-i2c.c

- It is important to write at first to MO_GP3_IO for cx88-tvaudio.c

- Use try_to_freeze() instead of refrigerator at msp3400.c

- Recognizing the MFPE05-2 Tuner at tveeprom.c

- Add new parameter to help identify radio chipsets at tuner module:
  show_i2c=1 will show 16 reading bytes from detected tuners.

- BTTV does generate some Unimplemented IOCTL log at tuner module:
  0x40046d11(dir=1,tp=0x6d,nr=17,sz=4) means that it is sending
  MSP3400 calls to non-msp3400 tuners. Warning eliminated.
  VIDIOSAUDIO is also called, so debug messages updated. It is still
  requiring IOCTL implementation.

- Added two more tuners.

- Add support for the SVideo input on the GDI Black Gold.
