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.

Fix minor locking issues in the Power Mac Uninorth PCI bridge driver.

- Call resource_int_value() once during attach, rather than within the
pci_(read|write)_config() code path; this avoids taking a blocking mutex
to read kenv variables.

- Use a spin lock to protect non-atomic config space accesses; this matches
the behavior of Darwin's AppleMacRiscPCI driver.

sys/powerpc: 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.

Reduce OFW PCI code duplication - involves ARM, PPC and SPARC64

Import portions of the PowerPC OF PCI implementation into new file
"ofwpci.c", common for other platforms. The files ofw_pci.c and ofw_pci.h
from sys/powerpc/ofw no longer exist. All required declarations are moved
to sys/dev/ofw/ofwpci.h. This creates a new ofw_pci_write_ivar() function
and modifies some others methods. Most functions contain existing ppc
implementations in the majority unchanged. Now there is no need to have
multiple identical copies of methods for various architectures.
