Google is pretty clear that the HVR 1110 IR chip is always at address
0x71 and the BeholdTV IR chip is always at address 0x2d. This
completes the list of IR device addresses for the SAA7134-based
adapters, and we no longer need to probe any of them.

Note: this goes on top of the other saa7134 patches I've sent earlier
today.
