ignore_pci: Add a proper stub attach routine

This isn't a bus driver, so an empty attach routine is more appropriate.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

proper defines for these constants.

In particular dev/acpica/acpi_pcib_pci.c returns -1000 as the
probe priority and it's expected that this driver gets to
attach over the common PCI bus drivers.

Don't return -10000 as the probe priority. That's lower than what
BUS_PROBE_HOOVER is. Drivers like proto(4), when compiled into the
kernel or preloaded, will render your system useless by virtue of
attaching to your PCI busses.

Return BUS_PROBE_GENERIC instead. It's just the next priority up
from BUS_PROBE_HOOVER. No other meaning has been give to its use.
While BUS_PROBE_DEFAULT seems like a better candidate, it's hard
not to think that there must be some reason why these drivers
return -10000 in the first place.

code to be compatible with older versions of FreeBSD.

Next phase in the PCI subsystem cleanup.

- Move PCI core code to dev/pci.
- Split bridge code out into separate modules.
- Remove the descriptive strings from the bridge drivers. If you
want to know what a device is, use pciconf. Add support for
broadly identifying devices based on class/subclass, and for
parsing a preloaded device identification database so that if
you want to waste the memory, you can identify *anything* we know
about.
- Remove machine-dependant code from the core PCI code. APIC interrupt
mapping is performed by shadowing the intline register in machine-
dependant code.
- Bring interrupt routing support to the Alpha
(although many platforms don't yet support routing or mapping
interrupts entirely correctly). This resulted in spamming
<sys/bus.h> into more places than it really should have gone.
- Put sys/dev on the kernel/modules include path. This avoids
having to change *all* the pci*.h includes.
