Rather than special-casing on POWER9, move the initialization of cpu_features and cpu_features2 to as early as possible, so that platform and MMU configuration can be based upon CPU features instead of specific CPUs if at all possible.

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.

Actually generating such executables requires a new version of binutils and a newer compiler (either GCC or clang) than GCC 4.2.1.
