pcmcia: remove unused flag, simplify headers
As we only provide one way to set up resources now, we can remove the resource-setup-related bitfield (except resource_setup_done). In addition, pcmcia_state only consisted of one entry, so remove this bitfield as well. Suggested-by: Komuro <komurojun-mbn@nifty.com> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
