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.
