pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (char)

Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of
requiring manual settings of PCMCIA_DEBUG. Only some rare extra debug checks
in cm4000_cs.c cm4040_cs.c are now hidden behind a "#ifdef CM4000_DEBUG"
or "#ifdef CM4040_DEBUG".

Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.
