- fix cut/paste problem. :-)
- don't forget to call isa_dmacascade()
- reset the port after we release resources.
That last one is a trap to watch out for.. The isa bus driver uses the
same port/irq/mem/etc variables for the initial probe hints as it does
for allocation/deallocation tracking. Releasing a resource clears the
variable and then you loose the hint during attach.. (ouch!)
had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go. The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa. I have only tested the EISA part of this so far.

hasseen_isadev so this will be less noisy when conflicts do exist.
Also eliminate redundant warnings about conflicts.

o For bt and aha only probe the one I/O range if a specific I/O is specified
in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.
