pcmcia: re-work pcmcia_request_irq()

Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:

- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.

- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
  clean up automatically on calls to pcmcia_disable_device() or
  device ejection.

- drivers still not capable of IRQF_SHARED (or not telling us so) may
  use the deprecated pcmcia_request_exclusive_irq() for the time
  being; they might receive a shared IRQ nonetheless.
