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.

The cs4232 and cs4236 are the same now and one can be removed.
Stanley tested this patch and it worked for him (cs4232 chip in Tecra 500).
I have tested it on Dell Latitude CP (cs4237b chip) which is now correctly recognized. Previously, it was recognized as a basic cs4236 chip. Also, I have tested it with Maxi Sound 32 PnP card (ISA PnP cs4236b) with success.
A side effect of this approach is that on ISA PnP cards the driver reports an error of PnP BIOS detection everytime it is loaded. This is due to driver rejecting the PnP BIOS initialization for ISA PnP cards. Probably, the earlier cs4232 driver worked the same way.
