pcmcia/ds.h: introduce helper for pcmcia_driver module boilerplate

Browse source 
Introduce the module_pcmcia_driver() macro which is a convenience macro
for pcmcia driver modules. It is intended to be used by pcmcia drivers
with init/exit sections that do nothing but register/unregister the
pcmcia driver.
