Sprinkle EARLY_DRIVER_MODULE around the tree

Mark some buses as BUS_PASS_BUS, and some resources as BUS_PASS_RESOURCE.
This also decouples some resource attachment orderings from being races by
device tree ordering, instead relying on the bus pass to provide the
ordering.

This was originally intended to support multipass suspend/resume, but it's
also needed on PowerMacs when using fdt, as the device tree seems to get
created in reverse of the OFW tree.

Rudimentary AER reading code for ddb(4).

This is very primitive code to inspect the PCI error state and AER
error state, dump the log and clear errors, from ddb.
pci_print_faulted_dev() is made external to allow calling it from
other places. It was called from NMI handler but this chunk is not
included.

Also there is a tunable-controlled code to clear AER on device attach,
disabled by default.

All this code was useful to me when I debugged ACPI_DMAR failures (not
faults) long time ago.

Add device location wiring to the pci bus.

This allows one to specify, for example, that if there's an igb card
in bus 12, slot 0, function 0, it should be assigned igb5. If there
isn't, or there's one in a different slot, normal numbering rules
apply (hinted units are skipped). Adding 'hint.igb.5.at="pci12:0:0"'
or 'hint.igb.5.at="pci0:12:0:0"' to /boot/device.hints will accomplish
this. The double quotes are important.

The kernel only accepts the strings (in shell notation):
pci$d:$b:$s:$f
and pci$b:$s:$f
where $d is the pci domain, $b is the pci bus number, $s is the slot
number and $f is the function number. A string compare is done with
the current device to avoid another string parser in the kernel. All
numbers are unsigned decimal without leading zeros.

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

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.

pci: fix write order when sizing BARs

According to the PCI Local Specification rev. 3.0 in case of a 64-bit
BAR both the low and the high parts of the register should be set to
~0 before attempting to read back the size.

So far I have found no single device that has problems with the
previous approach, but I think it's better to stay on the safe size.

This commit should not introduce any functional change.
