o Move PIOCSRESOURCE from pccard to pcic so the kernel can give pccardd
better hints as to what resources to use.
o Implement an undocumented hw.pcic.interrupt_route to allow people that
need to do so to route their interrupts in a non-standard way.
o Only preallocate a resource in probe if we're routing via pci.
o If we aren't routing via pci, then set the irq to use explicitly
to defeat the automatic IRQ routing of the pci layer.
This, with the pccardd code should be close to what can be committed
to -stable.
