pcmcia: IOCARD is also required for using IRQs
Dave Hinds pointed out to me that 37979e1546a7 will break b43 and ray_cs, as IOCARD is not -- as the name would suggest -- only needed for cards using IO ports. Instead, as it re-deines several pins, it is also required for using interrupts. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
