pcmcia: improve check for same card in slot after resume
During a suspend/resume cycle, an user may change the card in the PCMCIA/CardBus slot. The pcmcia_core can at least look at the socket state to check whether it is the same. For PCMCIA devices, move the detection and handling of such a change to ds.c. For CardBus devices, the PCI hotplug interface doesn't offer a "rescan" facility which also _removes_ devices no longer to be found behind a bridge. Therefore, remove and re-add all devices unconditionally.
