i386 and amd64 to make avoid legacy ISA I/O registers. Fixes issues with
ThinkPad T-series Dock II units as reported by sobrado@

Tested by myself, sthen, oga, kettenis, and jasper.

logic to be chipset dependent; no functional change yet.

based on the BIOS memory map.

and even then it didn't work. we have higher standards than this.

pointless and just makes the code different for no reason. This moves i386 and
amd64 bus_dma to being a lot closer to identical.
suggestion to just remove the prefix instead of merge them from deraadt@.
no objections art@, kettenis@, ok weingart@

All callers actually took all arguments to pci_intr_map from pci_attach_args
structs, so this simplifies code.
This also allows more complicated interrupt assignment schemes like the one
on sparc64.
This makes sparc64 pci interrupts work.
Inspired by the same change in NetBSD.

representation, this is needed for devices like cbb which pass
the interrupt line down to the cardbus attachment and not
getting the right line before pci_intr_map() has done it's
dirty deed.
tested on i386 by jason@, compiles on alpha by art@.
ppc and mveppc are to be test-compiled, but should work (;

run through the devices and programming the icu
and pci headers before real pci bus autoconf starts
and include all devices present on all pci busses,
to a per attached device routing in pci_intr_map().
this solves several cases of premature interrupts hanging
system due to absent interrupt handlers during autoconf.

fixes quite a few problems.
adds new option PCIBIOS_ADDR_FIXUP.
numerous extra fixes by me, also pointed out by other ppl,
such as avoid panics, ifdef on pciverbose, not diagnostic,
some other smaller knits; some have been forwarded back
to netbsd developers, some will go soon too.

so far, the other archs gets placeholders for now. I wrote a compatibility
layer for OpenBSD's old isadma code so we can still use our old
driver sources. They will however get changed to native bus_dma use,
on a case by case basis. Oh yes, I almost forgot, I kept our notion
of isadma being a device so DMA-less ISA-busses still work
