The public bus_release_resource() API still accepts both forms, but
the internal kobj method no longer passes the arguments.
Implementations which need the rid or type now use rman_get_rid() or
rman_get_type() to fetch the value from the allocated resource.

vgapci: Don't create a drm helper

Simply speaking, being started the drm-kmod driver should create sysfs helpers,
which is «drm» class devices, with the unit number 0, 128 and, perhaps 64.
If a drm helper created by vgapci driver with the corresponding unit number
exists then the drm-kmod driver initialize it by the device_initialize() lkpi
method, otherwise drm-kmod driver create new «drm» device.
For hw, where two or more different GPU installed, it's not guaranteed that
the order of loading GPU drivers will be the same as the vgapci devices numbered.
I.e., on hw where vgapci0 is Nvidia GPU and vgapci1 is Intel GPU, when drm-kmod
loaded first it will use drm0 helper of vgapci0 device.
There is no problem for drm-kmod driver unless we do not traverse device
tree, as needed for https://reviews.freebsd.org/D38545.

drm-kmod is ok for this change as it has fallback to create corresponding
drm device.

Add necessary bits for Linux KPI to work correctly on powerpc

PowerPC, and possibly other architectures, use different address ranges for
PCI space vs physical address space, which is only mapped at resource
activation time, when the BAR gets written. The DRM kernel modules do not
activate the rman resources, soas not to waste KVA, instead only mapping
parts of the PCI memory at a time. This introduces a
BUS_TRANSLATE_RESOURCE() method, implemented in the Open Firmware/FDT PCI
driver, to perform this necessary translation without activating the
resource.

In addition to system KPI changes, LinuxKPI is updated to handle a
big-endian host, by adding proper endian swaps to the I/O functions.

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.
