hda-intel - Fix codec probe with ATI controllers
[ALSA] hda-intel - Fix codec probe with ATI contorllers ATI controllers may have up to 4 codecs while ICH up to 3. Thus the earlier fix to change AZX_MAX_CODECS to 3 cause a regression on some devices that have the audio codec at bit#3. Now max codecs is defined according to the driver type, either 3 or 4. Currently 4 is set only to ATI chips. Other might need the same change, too.
