CONFIG_PCMCIA_IOCTL doesn't exist in Kconfig, therefore removing all
references for it from the source code. PCMCIA_IOCTL was removed partly
in a3f916f2c84f2b9e1d32cc0dbfe326a9e380dbfb, but there were a few pieces
scattered over the source tree, because they are never selected they can
be removed.

-    bind_request() and bind_device() are merged by now. Register_client()
-    is called right at the end of bind_request(), during the driver's
-    ->attach() call. Individual descriptions:
-
-    bind_request() connects a socket to a particular client driver.
-    It looks up the specified device ID in the list of registered
-    drivers, binds it to the socket, and tries to create an instance
-    of the device.  unbind_request() deletes a driver instance.
-
-    Bind_device() associates a device driver with a particular socket.
-    It is normally called by Driver Services after it has identified
-    a newly inserted card.  An instance of that driver will then be
-    eligible to register as a client of this socket.
-
-    Register_client() uses the dev_info_t handle to match the
-    caller with a socket.  The driver must have already been bound
-    to a socket with bind_device() -- in fact, bind_device()
-    allocates the client structure that will be used.
