thorpej 3835413bc1 Overhaul of the ISA autoconfiguration code to support direct 
configuration of devices logically attached to the ISA bus:

* Change the isa_attach_args to have arrays of io, mem, irq, drq
  resources.
* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
  isa_attach_args.  If either of these members are non-NULL,
  direct configuration of the bus is being performed.  Add an
  ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
  direct configuration is not being performed and the probe fucntion
  is returning success.
* Adapt device drivers -- currently, all driver probe routines return
  "no match" if ISA_DIRECT_CONFIG() evaluates to true.
