pccard: configure CLS on attach

For non hotplug PCI devices, the system firmware usually configures
CLS correctly.  For pccard devices system firmware can't do it and
Linux PCI layer doesn't do it either.  Unfortunately this leads to
poor performance for certain devices (sata_sil).  Unless MWI, which
requires separate configuration, is to be used, CLS doesn't affect
correctness, so the configuration should be harmless.

This patch makes pci_set_cacheline_size() always built and export it
and make pccard call it during attach.

Please note that some other PCI hotplug drivers (shpchp and pciehp)
also configure CLS on hotplug.
