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

Browse Source 
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.
