devpccard, pci: fix pccard support and handle pci expansion roms
let pci.c deal with the special cardbus controller bar0 and
expansion roms.
handle apic interrupt routing for devices behind a cardbus slot.
do not free the pcidev on card removal, as the drivers
most certanly are not prepared to handle this yet.
instead, we provide a pcidevfree() function that just unlinks
the device from pcilist and the parent bridge.
