pcmcia/staging: update comedi drivers

Browse Source 
Update comedi PCMCIA drivers to work with recent PCMCIA changes documented
in Documentation/pcmcia/driver-changes.txt:

- use pcmcia_config_loop()
- don't use PCMCIA_DEBUG, but use dev_dbg()
- don't use cs_error()
- re-use prod_id and card_id values already stored
