LinuxKPI: bitcount fix builds with gcc and older llvm

LLVM before 19 and gcc before 14 do not support __builtin_popcountg().
Use __const_bitcount<n> from sys/bitcount.h as a replacement in these
cases. This should still allow drm-kmod to build where the size needs
to be known at compile-time.

Remove the conditional for gcc around the iwlwifi modules build,
which was collateral damage in all this.

This adds the initial driver, and attached it to the hardware tracing

a given CPU.

Furthermore the most prolific instance for FreeBSD was the
Soekris Engineering vpn1201, vpn1211, vpn1401, and vpn1411
offerings. These are all 32-bit only processors. The i386
kernel was de-supported in 15.0.

random: add RDSEED as a provably unique entropy source

NIST SP800-90B allows for only a single entropy source to be claimed
in a FIPS-140-3 certificate. In addition, only hardware sources that
have a NIST Entropy Source Validation (ESV) certificate, backed by
a SP800-90B Entropy Assessment Report, are usable. Intel has obtained
ESV certificates for several of their processors, so RDSEED is a
FIPS-140-3 suitable entropy source.

However, even though RDRAND is seeded by RDSEED internally, RDRAND
would need a RBG certificate and CAVP testing run on the DRBG in order
to use it for FIPS-140-3 (SP800-90B) purposes. So we need to know
down in the CSPRNG-subsystem which source the entropy came from.

In light of the potential issues surrounding AMD Zen 5 CPU's RDSEED
implementation[*], allow RDSEED to be disabled in loader.conf.

thunderbolt: Import USB4 code

Add initial USB4 code written by Scott Long and originally passed on to
HPS (source: https://github.com/hselasky/usb4), minus the ICM code and
with some small fixes.

For context, older TB chips implemented the connection manager in
firmware (ICM) instead of in the OS (HCM), but maintaining the ICM code
would be a huge burden for not many chips.

Mostly completed work:

- Debug/trace framework.
- NHI controller driver.
- PCIe bridge driver.
- Router and config space layer handling (just reading in this commit).

Link to the email where Scott shared details about the initial USB4
work:

amdsmu: Initial work on a driver for the AMD SMU

Start work on a driver for the AMD SMU (system management unit), which
will eventually be used for getting S0ix statistics (e.g. how long the
CPU has spent in the deepest - S0i3 - sleep state during the last
sleep) as well as letting PMFW (power management firmware, running on
the SMU) know when we intend to enter and exit sleep. It is what's
responsible for actually turning off the VDD line to the CPU.

With this commit, amdsmu is just able to get the SMU's firmware version
on AMD Rembrandt, Phoenix, and Strix Point CPUs.

This is the equivalent to amd-pmc on Linux.

Import the Hardware Trace (HWT) framework.

The HWT framework provides infrastructure for hardware-assisted tracing. It
collects detailed information about software execution and records it as
"events" in highly compressed format into DRAM. The events cover information
about control flow changes of a program, whether branches taken or not,
exceptions taken, timing information, cycles elapsed and more. This allows
to reconstruct entire program flow of a given application.

This comes with separate machine-dependent tracing backends for trace
collection, trace decoder libraries and an instrumentation tool.
