pcmcia: use autoconfiguration feature for ioports and iomem

When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding
fields in struct pcmcia_device *p_dev->resource[0,1,2] are set
accordinly. Drivers wishing to override certain settings may do so in
the callback function, but they no longer need to parse the CIS entries
stored in cistpl_cftable_entry_t themselves.
