Remove all traces of support for ARM chips prior to the arm9 series. We never actually ran on these chips (other than using SA1 support in an emulator to do the early porting to FreeBSD long long ago). The clutter and complexity of some of this code keeps getting in the way of other maintenance, so it's time to go.
