[PCMCIA] unify yenta.c and pci_socket.c 

Linus said [on April 25th of this year]:
> There are two reasons I did pci_socket, and one of them is stale
> and the other one is a matter of taste.

As the second reason is stale now, too, unify yenta.c and
pci_socket.c.

/*
* Generic PCI pccard driver interface.
*
* (C) Copyright 1999 Linus Torvalds
*
* This implements the common parts of PCI pccard drivers,
* notably detection and infrastructure conversion (ie change
* from socket index to "struct pci_dev" etc)
*
* This does NOT implement the actual low-level driver details,
* and this has on purpose been left generic enough that it can
* be used to set up a PCI PCMCIA controller (ie non-cardbus),
* or to set up a controller.
*
* See for example the "yenta" driver for PCI cardbus controllers
* conforming to the yenta cardbus specifications.
