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.
