Bjorn Helgaas 96a6b9ad05 mips/PCI: get rid of device resource fixups 
Tell the PCI core about host bridge address translation so it can take
care of bus-to-resource conversion for us.

Here's the wrinkle on Cobalt: we can't generate normal I/O port addresses
on PCI because the GT-64111 doesn't do any address translation, so we have
this:

  CPU I/O port addresses		[io 0x0000-0xffffff]
  PCI bus I/O port addresses	[io 0x10000000-0x10ffffff]

Legacy-mode IDE controllers start out with the legacy bus addresses, e.g.,
0x1f0, assigned by pci_setup_device().  These are outside the range of
addresses GT-64111 can generate on PCI, but pcibios_fixup_device_resources()
converted them to CPU addresses anyway by adding io_offset.  Therefore, we
had to pre-adjust them in cobalt_legacy_ide_fixup().

With io_offset = 0xf0000000, we had this:

  res->start = 0x1f0	initialized in pci_setup_device()
  res->start = 0x100001f0	-= io_offset in cobalt_legacy_ide_fixup()
  res->start = 0x1f0	+= io_offset in pcibios_fixup_device_resources()

The difference after this patch is that the generic pci_bus_to_resource()
only adds the offset if the bus address is inside a host bridge window.
Since 0x1f0 is not a valid bus address and is not inside any windows, it is
unaffected, so we now have this:

  region->start = 0x1f0	initialized in pci_setup_device()
  res->start = 0x1f0	no offset by pci_bus_to_resource()

That means we can remove both pcibios_fixup_device_resources() and
cobalt_legacy_ide_fixup().

I would *rather* set the host bridge offset to zero (which corresponds
to what the GT-64111 actually does), and have both CPU and PCI addresses
of [io 0x10000000-0x10ffffff].  However, that would require changes to
generic code that assumes legacy I/O addresses, such as pic1_io_resource
([io 0x0020-0x00021]), and we'd have to keep a Cobalt IDE fixup.

Of course, none of this changes the fact that references to I/O port
0x1f0 actually go to port 0x100001f0, not 0x1f0, on the Cobalt PCI bus.
Fortunately the VT82C586 IDE controller only decodes the low 24 address
bits, so it does work.
