bt8xx/bttv-cards: module_param issue

I was looking at typos in MODULE_PARM_DESC() and I noticed a problem in drivers/media/pci/bt8xx/bttv-cards.c

MODULE_PARM_DESC(saa6588, "if 1, then load the saa6588 RDS module, default (0) is to use the card definition.");

The saa6588[] array is not set up as a module parameter so you can't actually use this setting. I don't know if it's better to delete it or enable it.
