pcmcia: rework the irq_req_t typedef
Most of the irq_req_t typedef'd struct can be re-worked quite
easily:
(1) IRQInfo2 was unused in any case, so drop it.
(2) IRQInfo1 was used write-only, so drop it.
(3) Instance (private data to be passed to the IRQ handler):
Most PCMCIA drivers using pcmcia_request_irq() to actually
register an IRQ handler set the "dev_id" to the same pointer
as the "priv" pointer in struct pcmcia_device. Modify the two
exceptions (ipwireless, ibmtr_cs) to also work this waym and
set the IRQ handler's "dev_id" to p_dev->priv unconditionally.
(4) Handler is to be of type irq_handler_t.
(5) Handler != NULL already tells whether an IRQ handler is present.
Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
irq_req_t.Attributes.
