Only change the fadt revision in acpidump on i386

There is a workaround in acpidump for an old IBM laptop. This is being
hit on a modern arm64 system causing acpidump to use the wrong field
when reading a later address.

As the laptop has a 32-bit CPU the only FreeBSD support for it is i386.
As such limit the workaround to that architecture.

The first is actually a bitfield. The second is printed in hex by
dmidecode, so uniformidy should be good.

various: general 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.

No functional change intended.
