thorpej 60530be43c Fix sizeof and whitespace bug from the script I'm using to do the
CFATTACH_DECL conversion.  (Grumble.)

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.

thorpej 712326ecbd Traditionally, the floppy controller was configured at 0x3f0 for 8 ports,
but the registers actually begin at 0x3f2, and this is what PNPBIOS reports
for the floppy controller resources.  Adjust the register offsets and the
mapping of them for the ISA front-end to compensate, so that the PNPBIOS
attachment of the floppy controller actually works.

thorpej 0cde36f780 Carve off the ISA configuration bits from the floppy driver. Driver is
still ISA-specific, but we can attach ISA instances with different
configuration mechanisms now.
