fix(unittests): fix checkpatch errors and warnings on .cpp files

This patch fixes all the errors and warnings reported by the
updated checkpatch.pl script with support for cpputest files.

xlat_tests_g1.cpp and xlat_tests_g2.cpp are excluded from
this patch as they will be fixed in a different patch.
