[PATCH] v4l: bttv driver update

This update for the bttv driver.  Changes:
 * adapt the driver to video-buf changes.
 * It also added sanity checks for the bt878 risc code buffer sizes.
 * adds support for new tv cards.
 * cleanup i2c driver autoload.
 * misc cleanups (msleep, ...).
 * fix IRQ bug when stopping vbi capture.
 * drop check for cx2388x (bt878 successor) and the printk saying bttv
   doesn't support these.
 * set i2c class correctly for dvb cards.
