The devmap variants used vm_offset_t for some reason, and a few places

along with similar casts for vm_size_t should just be removed and
instead permit the compiler to DTRT.)

[PowerPC] PowerMac timebase sync for G4

Summary:
Disable timebase on (some) AIM platforms (tested on PowerMac G4) prior
to synchronization.

Some platforms use a GPIO to enable and disable timebase, while others
use a platform function.

This mirrors 0d69f00b on mpc85xx.

Todo:
* Implement various G5 timebase controls.
* Print out platform code on unknown G5s so we can collect it.
* Change API to be give/take pairs like Linux does so it's possible to
do a software sync protocol.

newbus: Move from bus_child_{pnpinfo,location}_src to bus_child_{pnpinfo,location} with sbuf

Now that the upper layers all go through a layer to tie into these
information functions that translates an sbuf into char * and len. The
current interface suffers issues of what to do in cases of truncation,
etc. Instead, migrate all these functions to using struct sbuf and these
issues go away. The caller is also in charge of any memory allocation
and/or expansion that's needed during this process.

Create a bus_generic_child_{pnpinfo,location} and make it default. It
just returns success. This is for those busses that have no information
for these items. Migrate the now-empty routines to using this as
appropriate.

Document these new interfaces with man pages, and oversight from before.

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.

Clean up OF_getprop_alloc API

OF_getprop_alloc takes element size argument and returns number of
elements in the property. There are valid use cases for such behavior
but mostly API consumers pass 1 as element size to get string
properties. What API users would expect from OF_getprop_alloc is to be
a combination of malloc + OF_getprop with the same semantic of return
value. This patch modifies API signature to match these expectations.

For the valid use cases with element size != 1 and to reduce
modification scope new OF_getprop_alloc_multi function has been
introduced that behaves the same way OF_getprop_alloc behaved prior to
this patch.

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.
