arch/at91sam3x8e: update struct reg_sw_snapshot
...
With my discovery of how to actually use thumb2
instructions in assembly files, the layout of
register snapshot has changed because they are
now pushed in consecutive order.

The CNPL will make sure that absolutely no corporation is going to get
anywhere near Ardix -- exactly as it should be. Fuck you, corporations!

Ardix is being relicensed to GPL v3 or later. I have no idea whether you
can just do this if you feel like it or if it has any consequences, but
i kinda don't really care that much about it. Any changes made after
this commit will definitely fall under the GPL though, and considering
that only few things are really working yet anyways this is good enough
for me.

sched: properly disable the watchdog
...
I have no idea what the FUCK the Engineers at ARM were thinking when
they decided to disable EVERY SINGLE FUCKING CPU COMPONENT on system
reset, except the FUCKING WATCHDOG. But this change will prevent the
system from randomly firing a watchdog reset.
