arm/cpu: Replace license and copyright boilerplate by SPDX identfiers

This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.

While touching these files also do some minor comment reformatting to
get some uniform layout.
