hwpmc: tidy pcd_finalize methods

Make them a little bit more consistent with one another in terms of what
is done:
- Add/reduce assertions to what is most useful: a loop to ensure
pcpu_fini freed everything
- Add PMCDBG trace entries

The exception is the dmc620/cmn600 classes, which behave a little
differently, so leave them untouched.

hwpmc: pass pmc pointer to more class methods

In many cases this avoids an extra lookup, since the callers always have
pm at hand. We can also eliminate several assertions, mostly for pm !=
NULL. The class methods are an internal interface, and the callers
already handle such a scenario. No functional change intended.

This is because many of the functions are declared with a (void)
argument list, but defined with an empty argument list. Make the
definition match the declaration.

hwpmc: consistently validate PMC class in allocation method

It is always a good idea. In one case, attempting to allocate N+1 PMCs
from a class with N hardware counters would incorrectly attempt to
allocate from the next class in the list. Without this validation, this
can lead to all kinds of strange behaviour.

Since powerpc_allocate_pmc() is used by both the mpc7xxx and ppc970
classes, add a new global to track which is active (it will never be
both).

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.
