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

Browse Source 
Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of
requiring manual settings of PCMCIA_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.

All the PCMCIA modules use PCMCIA_DEBUG to control debugging. If
you do not define PCMCIA_DEBUG at all, all the debug code will be
left out. If you compile with PCMCIA_DEBUG=0, the debug code will
be present but disabled -- but it can then be enabled for specific
