ALSA: cs4236: cs4232 and cs4236 driver merge to solve PnP BIOS detection 

cs4232 and cs4236 driver merge to solve PnP BIOS detection.

Also, the patch adds recognition if the chip is cs4236b+
or earlier part. This unifies drivers for both cs4232
and cs4236+ chips. It allows to use the PnP BIOS
detection for the cs4236+ chips. Previously, only
the snd-cs4232 could be detected by the PnP BIOS.

The cs4232+ cards reports two separate PnP BIOS ids.

The patch adds search for the second id to find out
resources assigned to a control port.
