Some interrelated interrupt changes.
Frist, for pci slots, make the setup intr save the requested interrupt
vector and arg and return rather than passing it up to our parent. On
interrupts, we call this vector iff there's a card in the slot. This
should eliminate some of the hangs or "weird" messages that people see
when ejecting cards and also help close the race window somewhat.
Reading the pci bus one more time for this information is judged to be
an acceptible tradeoff since it is very very fast.
Cleanup a little how we detect unsupported cards. Only detect
unsupported cards (eg cardbus cards) on card insertion (or more
pedantically when a card is actually present). This should allow us
to change the message in the future to "cardbus card not supported
with OLDCARD" :-).
Note:
We may also consider this for the ISA bus case, but there the
reads are much more expensive and the location of the CD pin
status lines appears to be less standardized. Also, the ISA
management interrupt isn't shared with the card's interrupt.
The mutliplex the CSC and function interrupts bit also appears
to be non-standard (or at least not imlemented on all
bridges).
