NetBSD/sys/dev/cardbus/uhci_cardbus.c
drochner 36b6bc746c clean up the cardbus interrupt stuff: 
There were cardbus_intr_line_t and cardbus_intr_handle_t used intermixed
for the same variable, and that variable is pretty much useless because
cardbus doesn't follow the PCI interrupt swizzling etc scheme.
Useless interrupt numbers were printed on cardbus device attach.
So as a first step to sanity, kill cardbus_intr_handle_t and poison
cardbus_intr_line_t to discourage printing it as a %d.
Use cardbus_intr_line_t consistently throughout the code.
Remove the "interrupting at foo" messages because the information
is misleading. We could come up with a better interrupt vector
information, but because cardbus interrupts are mediated by pccbb
it would still be misleading.
