V4L/DVB (5482): Bttv: automatically load dvb-bt8xx for bttv cards with dvb
This patch causes the bttv driver to automatically load the dvb-bt8xx module
for bttv/dvb hybrid cards. Successfully tested with a pcHDTV HD-2000 card.
This patch is based on the recent patches to enable autoloading of cx88-dvb,
cx88-blackbird and saa7134-dvb.
