x86: Keep cumulative MCA statistics in the kernel

Keeping cumulative MCA statistics in the kernel provides a way for
users to get an accurate count of various kinds of errors reported
by the CPU.

After ca8929d2a3e9b9df31d2e487377f99d7c39aa01d, it is possible that
the kernel will drop the record of some MCA interrupts. Moreover, this
provides a cheaper interface to obtain statistics if that is the only
reason a user is processing MCA logs.

sys/x86: 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.
