pcmcia: setup IRQ to be used by PCMCIA drivers at card insert
Setup the IRQ to be used by PCMCIA drivers already during the device registration stage, making use of a new function pcmcia_setup_irq(). This will allow us to get rid of quite a lot of indirection in the future. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
