ng_ubt(4): do not attach Realtek 87XX/88XX adaptors in bootloader mode.

Attempt to initialize FreeBSD bluetooth stack while such a device is in
bootloader mode locks the adapter hardly so it requires power on/off
cycle to restore.

This change blocks ng_ubt attachment unless operational firmware is
loaded thus preventing the lock up.

If users want to disable isochronous transfers, which cause high

sysctl(8) or as a loader.conf(5) tunable.

ng_ubt: Avoid attaching to several newer Intel controllers

Like other Intel controllers, these require firmware to be loaded, and
generic ng_ubt attach causes them to lock up until a power cycle.
However, their firmware interface for querying version info and loading
operational firmware is different from that implemented by ng_ubt_intel
and iwmbtfw, so they are not usable yet. Just disable attach for now to
avoid stalls during USB device enumeration.

sys: 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.
