V4L/DVB (13446): ivtv: Add more explicit detection of known IR devices for Hauppauge cards

Avoid legacy IR I2C probing for PVR-150, PVR-500, and PVR-350 cards.  This
still probes, but restricts the possbile addresses probed per card.
Also removed legacy probe addresses for the KNC and PixelView cards which are
not supported by ivtv as far as I know.
