pcmcia: use dynamic debug instead of custom infrastructure
Use the generic "dynamic debug" infrastructure instead of
CONIG_PCMCIA_DEBUG in the PCMCIA core (pcmcia.ko and pcmcia_core.ko). To
enable debugging, enable CONFIG_DYNAMIC_DEBUG, mount debugfs and
$ echo -n 'module pcmcia_core +p' > /sys/kernel/debug/dynamic_debug/control
for the complete module "pcmcia_core", for example. For more detailled
instructions, please see Documentation/dynamic-debug-howto.txt
