stats: Update ARM stats to include programmable oscillators

tests: Update regressions for the new kernels and various preceeding fixes.

tests: update reference outputs

Apparently only stats.txt was updated the last time, so
this changeset updates other reference output files
(config.ini, simout, simerr, ruby.stats) so that
test output diffs should not be cluttered with irrelevant
changes. There are a few stats.txt updates too, but
they are in the minority.

ARM: update stats for clock frequency fix.

SE/FS: Make both SE and FS tests available all the time.
