[ALSA] HDA-Intel - Add support for RV610/RV630 HDMI audio

The Audio interface on HD2400/HD2600 cards isn't currently detected by
snd-hda-intel. I added missing pci device ids for RV610 and RV630, but
I only had a HD2400 pro card to test, where now the audio interface is
detected (and no need to change patch_atihdmi.c, as the codec vendor id
remains 0x1002aa01 for which we already have an entry there). I also
couldn't test if sound pass-trough is ok (and I don't know how to), but
at least now the device is detected.
