[PATCH] pcmcia: update vrc4171_card

These patches add a new interface for adding and removing I/O and mem
resources which are made available to 16-bit PCMCIA devices (content of
/etc/pcmcia/config.opts ) on non-statically mapped sockets.  Also, they
continue the device model integration of the PCMCIA subsystem, and provide
some output about PCMCIA devices via sysfs.

This patch updates vrc4171 pcmcia driver.
