[PATCH] pcmcia: remove export of pcmcia_release_configuration

Handle the _modifying_ operation sm91c92_cs requires in pcmcia_modify_configuration, so that the only remaining users of pcmcia_release_configuration() are within the pcmcia core module. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
